Description
Technical field
The present invention relates to the gas tunnel technical field of construction, especially a kind of method for evaluating hazard of gas tunnel and facilities and equipments thereof.
Background technology
The increasing that infrastructure construction is dropped into along with country and the enforcement of strategy to develop western regions, the construction of high-grade highway, railway from the coastland southwester, the northwest mountainous terrain extends, at these regional building highways, railway an outstanding feature is arranged, the construction that is exactly roads and tunnels is more, and passes through coal measure strata and compose the gas tunnel of depositing the high pressure coal seam also more and more common.Along with the increase of building vcehicular tunnel in recent years in coal measure strata, security incident is also in corresponding increase.In coal measure strata, build the tunnel and have two technical difficulties: the one, the coal measure strata majority contains gas, and gas explosion danger is arranged; The 2nd, the stratum that gas pressure is high exists the outstanding possibility of coal and gas, and under the acting in conjunction of terrestrial stress and gas, broken coal and gas spray suddenly, cause disaster.Therefore, we are necessary gas tunnel is carried out dangerous risk assessment.
Discussion about risk, be found in the earliest in the economics research in 19 end of the centurys in the west, and risk and risk management begin all to have obtained development in various degree in fields such as economics, sociology, management science, environmental science and engineering designs the 1950's as a knowledge.At present, risk definition and computing method that the United Nations provides are admitted by numerous scholars and associated mechanisms gradually, and obtain promoting and the developing application at different ambits gradually, and its taproot is dangerous and vulnerability comprehensive evaluation.And Geological Hazards Risk Evaluation is exactly that certain area or the historical disaster activity situation of certain hidden danger point, natural conditions, geologic media condition, human engineering economic activity situation etc. are carried out analysis-by-synthesis, thereby definite its jeopardizes the probability size of the disaster incident of human life's property safety.Geological Hazards Risk Evaluation is the basis of risk management and disaster management, is the important step in the hazards control work, for ensureing that people's life and property safety are most important; Also being the foundation of all kinds of engineering Authorize to Invest simultaneously, is to guarantee that engineering obtains the basic guarantee of economic benefit, social benefit, environmental benefit; Be one and have the important subject of realistic meaning and the non-engineering important measures of disaster mitigation loss, its achievement in research is with a wide range of applications.In recent years, along with develop rapidly economic and society, geologic hazard is more and more outstanding to socioeconomic harm.Therefore Geological Hazards Risk Evaluation also more and more becomes the focus of research.
In recent decades, China's Geological Hazards Risk Evaluation has also obtained extensively and again developing by leaps and bounds.And in the research of many geologic hazards, be the most deep and system for the research of earthquake, landslide and rubble flow.This mainly be because earthquake, landslide, rubble flow are China distribute the most extensive, harm is the most serious, 3 kinds of geologic hazards having the greatest impact.Therefore, the achievement in research of these 3 kinds of geologic hazards is also given prominence to (Li Kuo etc., 2007) the most.And the research that the gas tunnel security detects is not also launched, be not in full swing in other words, especially the index system of this respect is not also set up.Therefore, carry out gas tunnel security detection and have very important realistic meaning.
Summary of the invention
The purpose of this invention is to provide a kind of method for evaluating hazard of gas tunnel,, gas tunnel is carried out hazard assessment in order to formulate the dangerous engineering measure that takes place of reply early.
The present invention is a kind of method for evaluating hazard of gas tunnel and facilities and equipments thereof.A kind of method for evaluating hazard of gas tunnel is characterized in that, at first definite ten hazard of gas tunnel indexs are measured and judged in the gas tunnel major influence factors, according to hazard of gas tunnel index hierarchical table
Hazard of gas tunnel index hierarchical table
In the criteria for classifying, measuring and judged result incorporates in the table grade accordingly into, provide scoring, calculate hazard of gas tunnel index RTC=R then

10, the gas tunnel safe coefficient is a safety when RCT＜25, and the gas tunnel safe coefficient is a basic security when 25＜RCT＜50, and the gas tunnel safe coefficient is dangerous when 50＜RCT＜75, and the gas tunnel safe coefficient be danger when RCT 〉=75.In the formula, RTC (Risk of Gas Tunnel Classify) expression hazard of gas tunnel index, RTC score value scope is 0～100, its value is big more, the easy more generation gas accident in tunnel.The equipment of a kind of enforcement said method (method for evaluating hazard of gas tunnel) is characterized in that,
1) sets up hazard of gas tunnel index hierarchical table storer (1), safe class corresponding tables storer (6) and table memory (2);
2) the engineering coding is input to data processor (3), data processor (3) is read dangerous index evaluation empty forms from table memory (2), the dangerous achievement data in tunnel (4) that will record in the gas tunnel work area be input in the dangerous index evaluation empty forms in the data processor (3), simultaneously with hazard of gas tunnel index hierarchical table storer (1) in index compare classification;
3) in data processor (3), carry out quantitative assignment to sorting out the result, and according to the dangerous index RTC numerical value of formula (1) calculating, and demonstration numerical value, simultaneously numerical value is incorporated into the RTC numerical range in the safe class corresponding tables storer (6), determine safe class according to the scope under the shown numerical value;
4) data processor (3) outputs to output device (5) with the safe class result of RTC numerical range correspondence.
Ten computereses of estimating the gas tunnel safety indexes are encoded to the engineering coding, and the security of its safe class I, II, III, IV is successively decreased successively.
The criteria for classifying of some index grades is described as follows in the hazard of gas tunnel index hierarchical table:
