【摘要】：為研究地質(zhì)災害對國道G345山區(qū)路段工程建設的影響,為國道線路設計提供依據(jù),選取地形地貌、巖土體類型、斜坡結(jié)構(gòu)、降水量、河流沖刷程度、地質(zhì)災害發(fā)育現(xiàn)狀6個影響因素,采用模糊綜合評判法和信息量法對國道G345鎮(zhèn)安金鐘至木王林場段公路進行了地質(zhì)災害危險性評價,將研究區(qū)劃分為地質(zhì)災害危險性大、中等和小3個區(qū)。結(jié)果表明:模糊綜合評判模型和信息量模型評價結(jié)果均與研究區(qū)實際情況基本相符,危險性大區(qū)和危險性中等區(qū)主要分布在路基部分和隧道段。通過與實際情況比較分析,對于地質(zhì)災害嚴重區(qū),模糊綜合評判模型優(yōu)于信息量模型;對于地質(zhì)災害較嚴重區(qū),信息量模型優(yōu)于模糊綜合評判模型。
[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.
