【摘要】：为研究地质灾害对国道G345山区路段工程建设的影响,为国道线路设计提供依据,选取地形地貌、岩土体类型、斜坡结构、降水量、河流冲刷程度、地质灾害发育现状6个影响因素,采用模糊综合评判法和信息量法对国道G345镇安金钟至木王林场段公路进行了地质灾害危险性评价,将研究区划分为地质灾害危险性大、中等和小3个区。结果表明:模糊综合评判模型和信息量模型评价结果均与研究区实际情况基本相符,危险性大区和危险性中等区主要分布在路基部分和隧道段。通过与实际情况比较分析,对于地质灾害严重区,模糊综合评判模型优于信息量模型;对于地质灾害较严重区,信息量模型优于模糊综合评判模型。
[Abstract]:In order to study the influence of geological hazards on the engineering construction of the national highway G345 mountain section, and to provide the basis for the design of the national highway line, the terrain and geomorphology, the types of rock and soil, the slope structure, the precipitation and the river scour degree are selected. In this paper, the authors use fuzzy comprehensive evaluation method and information quantity method to evaluate the geological hazard risk of highway G345 from Zhenan Jinzhong to Muwang Forest Fangang, and divide the study area into geological hazard risk. The results show that the evaluation results of the fuzzy comprehensive evaluation model and the information quantity model are basically consistent with the actual situation in the study area. The risk area and the middle risk area are mainly distributed in the subgrade and the tunnel section. By comparing with the actual situation, the fuzzy comprehensive evaluation model is superior to the information quantity model for the serious geological hazard area, and for the serious geological hazard area, the fuzzy comprehensive evaluation model is superior to the information quantity model for the serious geological hazard area. The information quantity model is superior to the fuzzy comprehensive evaluation model.
