襄渝铁路(胡家营-万源段)地质灾害发育特征及危险性评价
Distributing Character and Risk Assessment of Geological Disasters along Xiangyang-Chongqing Railway (Hujiaying-Wanyuan Segment)
摘要
Abstract
The landslide,rockfall,topsoil slip and debris flow was founded along the Xiangyang-Chongqing Railway (Hujiaying-Wanyuan Segment) through detailed investigation and analysis.Rock fall is the main natural disaster among these disasters,exceeds the three-quarters of the total number of disasters,followed by topsoil slip,landslide and debris flow.Composite index analytic hierarchy process method was adopted to evaluate the hazard of every single point of geological disasters based on the detailed investigation and analysis.The results of assessment indicate that the numbers of hazard points,which belong very serious,serious,and medium and minor,are 19,55,103 and 44,respectively.The geological disaster risk assessment model of the whole line (Hujiaying-Wanyuan Segment) was built through collecting all the hazard points along this line.Adopted the fuzzy comprehensive evaluation method,the divisional evaluation is proceeded and the results indicate that the length of very serious region is 0km and the lengths of high hazard,medium hazard and low hazard regions are 179km,55km and 55km,respectively,among the assessment length of 289km.关键词
