In recent years, urban rail transit such as subways, light rails and the like rapidly developed in China has higher and higher requirements on safe running of trains and rapid safety of passengers; because the track structure of urban rail transit adopts a concrete integral ballast bed, the track engineering is positioned once and can not be regulated; the track laying base mark is a track laying control point of a high-standard track concrete integral ballast bed, so that the measurement work of the track laying requirement is met with high precision, and the key point is that the track laying base mark is used for guaranteeing the design position and the line parameter of the track and guaranteeing the limit requirement of a driving tunnel; the method has stricter requirements on the rail laying precision, so that the accurate rail laying standard is an important link for ensuring the high-precision construction of the subway rail; the track laying base mark is provided with marks of accurate plane coordinates and elevation; the control basic mark and the encryption basic mark can be divided according to the precision level; two kinds of embedded positions of the track laying base mark are arranged on one side of a line center line or a line center line; the main work of the track engineering measurement is track laying basic mark measurement; the essence is that according to the requirements of the design line and the integrated design drawing of the track laying, a mark with accurate plane coordinates and elevation is tested on the line or one side of the line at certain intervals to be used as the plane and elevation basis of the track laying;
With the rapid development of the building industry in recent years, building related professions are also attracting attention, and meanwhile, government departments also put forth related requirements in the design and construction process; BIM is becoming more and more widespread in domestic engineering project construction work as well; the application of BIM technology in construction is embodied in various aspects, such as drawing deepening, construction simulation, scheme simulation, construction management and the like; in terms of BIM technology, the application of the BIM technology in engineering project design, construction, operation and maintenance after completion and other stages can play a great role; along with the application of BIM technology to each stage in the whole life cycle of the building industry, the measurement process is required to be introduced in each stage of the building industry, and the measurement requirements of each field are greatly changed; for example, previous two-dimensional maps have not been able to meet the measurement requirements of the relevant field; even three-dimensional maps are being eliminated, and at least 4D maps containing other elements such as time information are required; foreign related scholars are led ahead in researching BIM technology, and reference is provided for solving engineering practical problems by the BIM technology through application effect analysis of the BIM technology in practical engineering; application research of BIM technology in subway stations is carried out, application of BIM technology in subway station modeling and data management is researched, modeling staff identifies different components of a building through embedding information in a model, a construction process is simulated, BIM software is used for building the model, different component attributes are defined, and model data information is linked to improve management quality; the BIM technology is also widely focused in the construction field, a reference plane is used for positioning a model component in the modeling process, and a research result provides support for tunnel informatization modeling; the method comprises the steps of applying an information technology to urban tunnel engineering projects, and sorting shield posture and tunnel monitoring data of a shield machine through the application of the information technology;
The BIM technology is gradually developed in the construction industry of China, the multi-specialized collaborative design not only can show the value of the BIM technology, but also is the future development direction of the BIM technology, and the integrated design route of the collaborative design under the BIM platform is combined with case carding, so that a BIM integrated multi-specialized collaborative design flow frame is explored and constructed; BIM technical routes of three stages of highway engineering design, construction and operation and maintenance are provided for development of BIM technology in highway design; integrating various graphic information by adopting BIM technology to realize online modification of data information; the BIM technology is utilized to conduct research on bridge rapid modeling, the disadvantages of the current low-efficiency manual modeling are analyzed, and the advantage comparison is conducted on the mainstream modeling software in the current market;
