All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, a fire safety assessment method for an ancient architecture includes:
s1, acquiring building information of an ancient cultural relic building;
s2, acquiring corresponding environment change information according to the building information of the ancient cultural relic building;
and S3, obtaining a fire risk assessment result of the ancient relic building according to the building information of the ancient relic building and the corresponding environment change information.
The step S1 specifically comprises the following steps:
the method comprises the steps of utilizing existing building information of an ancient cultural relic building and historical damage information of the ancient cultural relic building as building information of the ancient cultural relic building;
the existing building information of the ancient cultural relic building comprises position information of the ancient cultural relic building, damage degree of building materials, temperature of the building materials, humidity of the building materials, area of the building and free activity degree of space of the building; the historical damage information for ancient architecture includes load thresholds for building damage, humidity thresholds for building materials, and temperature thresholds for building materials.
In this embodiment, the damage degree of the building material is specifically based on the crack length of the building material, the damage degree of the wall body, the crack width of the building material, and the extraction distance of the beam end are related to the inclination degree of the door and window. For example, if a crack with a width of 1-2 mm appears on a brick wall between nature, the damage degree of the building material is very slight damage; if cracks with the width smaller than 4mm appear on the brick wall between the nature and the total width of a plurality of cracks is smaller than 10mm, the damage degree of the building material is slight damage; if cracks with the width smaller than 15mm appear on a brick wall between nature, the total width of a plurality of cracks is smaller than 30mm, the lengths of the cracks on a reinforced concrete beam and a reinforced concrete column are smaller than 1/3 section height, the extraction of the beam end is smaller than 20mm, horizontal cracks appear on the brick column, the lengths of the cracks are larger than 1/2 section side length, and a door and a window are slightly askew, so that the damage degree of the building material is moderate damage; if the natural brick wall has serious cross cracks and vertical through cracks, and the wall body has serious outer bulge and deflection, the reinforced concrete beam and column cracks are through along the section, and the extraction of the beam end is more than 60mm; the brick column has horizontal dislocation larger than 25mm, and the damage degree of the building material is heavy damage when the brick column is in danger of collapse.
The step S2 specifically comprises the following steps:
s2-1, acquiring temperature change information of the ancient relic building corresponding to an environment prediction period according to the position information of the ancient relic building;
s2-2, acquiring humidity change information of the ancient relic building corresponding to an environment prediction period according to the position information of the ancient relic building;
s2-3, acquiring sun exposure time length information of the ancient relic building corresponding to the environment prediction period according to the position information of the ancient relic building;
s2-4, acquiring corresponding environment change information by using the temperature change information, the humidity change information and the insolation time length information of the prediction period.
In this embodiment, according to the environmental change amplitude of the area where the ancient architecture is located and the time period required for arranging the opening of the ancient architecture, environmental change information in a prediction period, for example, the time period required for arranging the opening of the ancient architecture in advance and the flow of open people on holidays, at least environmental change information in a future week needs to be collected, so as to facilitate management of the cultural workers.
The step S3 specifically comprises the following steps:
s3-1, constructing a three-dimensional simulation model of the ancient relic building according to the existing building information of the ancient relic building;
s3-2, obtaining fire risk coefficients of all areas of the ancient relic building according to the existing building information and the historical damage information of the ancient relic building;
s3-3, establishing a panoramic simulation model of the ancient relic building based on a three-dimensional simulation model of the ancient relic building according to the fire risk coefficients and the traffic conditions of people in each area of the ancient relic building;
s3-4, inputting the environmental change information of the ancient relic building into a panoramic simulation model of the ancient relic building, and performing fire-fighting simulation on the ancient relic building to obtain a fire-fighting risk assessment result of the ancient relic building.
The step S3-2 specifically comprises the following steps:
s3-2-1, obtaining natural disaster risk coefficients r of all areas of the ancient relic building by using the existing building information of the ancient relic building, the material humidity critical value of the ancient relic building and the material temperature critical value of the ancient relic building 1 ；
S3-2-2, obtaining an artificial disaster risk coefficient r2 of each area of the ancient relic building by utilizing the existing building information of the ancient relic building and the load critical value of the ancient relic building;
s3-2-3, acquiring the weight t1 of the natural disaster risk coefficient and the weight t2 of the artificial disaster risk coefficient according to the corresponding environmental change information of the ancient architecture;
s3-2-4, weight t of natural disaster risk coefficient according to each area of ancient architecture 1 Weight t of artificial disaster risk coefficient 2 Risk factor r of natural disasters 1 Artificial and man-madeDisaster risk coefficient r 2 The calculation formula for obtaining the fire risk coefficient p of each area of the ancient cultural relic building is as follows:。
in this embodiment, the natural disaster risk coefficient r1 of each area of the ancient architecture is obtained by using the temperature of the building material of the existing building information of the ancient architecture, the humidity of the building material, and the material humidity critical value of the ancient architecture and the material temperature critical value of the ancient architecture, the difference between the temperature of the building material and the material temperature critical value of the ancient architecture is inversely proportional to the natural disaster risk coefficient r1, and the difference between the humidity of the building material and the material humidity critical value of the ancient architecture is inversely proportional to the natural disaster risk coefficient r 1. The damage degree of building materials, the area of a building, the space free activity degree of the building and the load critical value of the ancient architecture are utilized to obtain the artificial disaster risk coefficient r2 of each area of the ancient architecture, the damage degree of the building materials is in direct proportion to the artificial disaster risk coefficient r2, the area of the building is in inverse proportion to the artificial disaster risk coefficient r2, the space free activity degree of the building is in inverse proportion to the artificial disaster risk coefficient r2, and the load critical value of the ancient architecture is in inverse proportion to the artificial disaster risk coefficient r 2.
For example, ancient architecture generally adopts strict axisymmetric layout and has smaller window opening area on room walls around the building style which are relatively closed, which is not beneficial to ventilation and lighting in the room, and particularly, the phenomenon of 'moisture returning' easily occurs in the sunny days of rain, and the humidity critical value of the ancient architecture is 80 to 90 percent of the current humidity.
For example, in the building materials, wood is mostly selected, chemical reactions such as oxidative decomposition and the like can be accelerated by rapid changes of high temperature, the deterioration and aging speeds of organic materials such as building wood are higher, meanwhile, the activity of fungus species of the insect can be increased under the high temperature condition, the propagation of the fungus species can be promoted, and the ancient building is further endangered. The repeated expansion and contraction caused by the abrupt change of temperature can easily cause the elastic fatigue of cultural relics, and the inlaid or combined parts can easily loosen, so that the relative temperature critical value of wood is low in most building materials.
For example, the original building which maintains the original shape and building style is required, and the space free activity of the building is relatively small in order to maintain the original shape and not perform large-movement space adjustment.
For example, the open immovable ancient architecture has various dangerous cases such as wall cracking and collapse, foundation collapse, building collapse and the like, and has been repaired for many times, but when the open immovable ancient architecture is in rainy seasons, foundation damage is easy to cause, so that settlement is uneven, in addition, some walls of the ancient architecture are clay blanks and rammed earth walls, so that the walls are weak, collapse, cracking, sinking and the like are easy to occur, and the load critical value is relatively small when the ancient architecture is in a rainy season environment and the building state is easy to cause safety accidents.
The step S3-2-3 specifically comprises the following steps:
s3-2-3-1, acquiring the time ratio x of the temperature exceeding the temperature critical value of the building material in the prediction period by utilizing the temperature change information of the corresponding environment prediction period of the ancient cultural relic building;
s3-2-3-2, acquiring the time ratio y of humidity exceeding the humidity critical value of the building material in the prediction period by utilizing the humidity change information of the corresponding environment prediction period of the ancient cultural relic building;
s3-2-3-3, acquiring the sun exposure length z of the ancient relics by utilizing sun exposure time length information of a predicted period of the corresponding environment of the ancient relics;
s3-2-3-4, acquiring the time duty w of the rainy day in the prediction period by utilizing the environmental change information of the ancient cultural relic building corresponding to the environmental prediction period;
s3-2-3-5, obtaining weight t of natural disaster risk coefficient by using x, y, z and w 1 And weight t of artificial disaster risk coefficient 2 。
The step S3-2-3-5 specifically comprises the following steps:
s3-2-3-5-1, respectively setting scales for x, y, z and w according to different seasons;
s3-2-3-5-2, obtaining weight t of natural disaster risk coefficient based on analytic hierarchy process by using scale data of x, y, z and w 1 ；
S3-2-3-5-3 weight t according to natural disaster risk coefficient 1 Obtaining weight t of artificial disaster risk coefficient 2 ；
Wherein t is 1 +t 2 =1。
In this embodiment, scales are set for x, y, z and w according to different seasons, and if fire safety of an ancient cultural relic building in a spring period is evaluated, the scales set for x, y, z and w are respectively: 2. 3, 1, 3; if the fire safety of the ancient cultural relic building in the summer time is evaluated, the set scales of x, y, z and w are respectively as follows: 4. 3, 4 and 2; if the fire safety of the ancient cultural relic building in the autumn time end is evaluated, the set scales of x, y, z and w are respectively as follows: 3. 4, 2; if the fire safety of the ancient cultural relic building in the winter time is evaluated, the set scales of x, y, z and w are respectively as follows: 3. 2, 2 and 3. In the concrete implementation, according to the change of temperature, humidity and sunlight duration when seasons of the geographical position of the ancient cultural relic building alternate, the set values of x, y, z and w are adjusted, so that the comprehensiveness of judging the fire risk coefficient of the ancient cultural relic building is realized.
The step S3-4 specifically comprises the following steps:
s3-4-1, obtaining open information of each area of the ancient architecture under the environment change condition according to the fire risk coefficient of each area of the ancient architecture;
s3-4-2, obtaining the flow path superposition information of each area of the ancient relic building according to the opening information and the flow condition of each area of the ancient relic building;
s3-4-3, obtaining collapse conditions of all areas of the ancient architecture according to the overlapping information of the traffic flow paths of all areas of the ancient architecture;
s3-4-4, establishing a panoramic simulation model of the ancient relic building based on the three-dimensional simulation model of the ancient relic building according to the collapse condition of each area of the ancient relic building.
The step S3-4-3 specifically comprises the following steps:
judging whether the people flow path overlap ratio of the building area at the same time exceeds r, if yes, collapsing the building area, otherwise, collapsing the building area;
wherein the method comprises the steps ofA is a load critical value of building damage, and b is a traffic load value.
