Collapse Risk Assessment And Control Measures Research About New Liangfengya Tunnel

During the construction in the underground of the tunnel, The engineering geological disasters always cause the accident, It make us concern the risks between the constructions about the tunnel. We base on the actual situation in the new Liangfengya tunnel, study the probabilities of the landslides in the tunnel. For the case of the landslides about the constructions, It should be studied by the control measures. Our subject of the paper rely on the project of the new Liangfengya tunnel. It focuses on the risk assessment about the situations of the tunnel collapse. As follows, we need to expand the main contents, There are the four areas:the first:By reviewing relevant literature and materials, We can get the tunnel collapse different categories, and discuss a lot of factors about all aspects of the tunnel. It could provide a reference for index factor.the second:By the long practice in the project section, I read the regional geology and the manuals, then get a comprehensive understanding about the engineering geology and hydrology in the tunnel site. We should screen out several factors from the tunnel, As the later evaluation factors of the evaluation system, statistics 90 tunnel collapses which occurred in recent years. As the origin of quantitative indicators in the risk assessment system.the third:We can find a lot of drawbacks in the elaborate with the AHP. So It should be used another more object and rational assessment methods in my paper, each index factor takes the value of quantify and dimension treatment. By basing on the extension theory, We can determine the correlation by the simple correlation function, then obtain each factor weight with some formulas, create correlation function about tunnel collapse hazard degree,the forth:The control measures of the tunnel collapse is a important part in my paper. For the part of the sections which may be occur collapse in the result of the assessment. We need use geological survey、 geophysical technology and other means to predict the situation in front of Face Meets about the above assessment result, then arrange the reasonable initial support tools and advanced support tools...
