【摘要】：為研究地質(zhì)災(zāi)害對(duì)國(guó)道G345山區(qū)路段工程建設(shè)的影響,為國(guó)道線路設(shè)計(jì)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(zāi)害發(fā)育現(xiàn)狀6個(gè)影響因素,采用模糊綜合評(píng)判法和信息量法對(duì)國(guó)道G345鎮(zhèn)安金鐘至木王林場(chǎng)段公路進(jìn)行了地質(zhì)災(zāi)害危險(xiǎn)性評(píng)價(jià),將研究區(qū)劃分為地質(zhì)災(zāi)害危險(xiǎn)性大、中等和小3個(gè)區(qū)。結(jié)果表明:模糊綜合評(píng)判模型和信息量模型評(píng)價(jià)結(jié)果均與研究區(qū)實(shí)際情況基本相符,危險(xiǎn)性大區(qū)和危險(xiǎn)性中等區(qū)主要分布在路基部分和隧道段。通過(guò)與實(shí)際情況比較分析,對(duì)于地質(zhì)災(zāi)害嚴(yán)重區(qū),模糊綜合評(píng)判模型優(yōu)于信息量模型;對(duì)于地質(zhì)災(zāi)害較嚴(yán)重區(qū),信息量模型優(yōu)于模糊綜合評(píng)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.
