Risk Assessment of Unfavorable Geological Bodies along the Highway Project in Guide Basin
摘要
Abstract
122 unfavorable geological bodies such as landslide,collapse,debris flow and freeze-thaw mudflow in the study area were obtained by remote sensing interpretation and field investigation on both sides of the design center route and comparison route of the capacity expansion project of Guide Basin Section of Qinghai S101 Line.3 first-level evaluation factors and 10 second-level evaluation factors were selected.The genetic algorithm was used to optimize the calculation of the weight of evaluation factors in the analytic hierarchy process,and the fuzzy comprehensive evaluation method was used to comprehensively evaluate the risk level of unfavorable geological bodies in the study area.The result shows that,the areas with high risk of unfavorable geological bodies in the study area are mainly distributed in the Neogene and Paleogene red beds with steep slope,low vegetation coverage and faults.The total length of the section of the central route threatened by the unfavorable geological body is less than that of the comparison route.Therefore,GA-AHP-fuzzy comprehensive evaluation yields higher accuracy.关键词
