鲁班崖滑坡位于国道G212线K365+832～K366+140处,威胁着国道的安全运行。通过实地调查,对鲁班崖滑坡的结构特征、成因特征及活动趋势进行了较为详细的分析。在此基础上,以地层岩性、地质构造、地形地貌、地下水和降雨为一级评价因子,建立了滑坡稳定性评价的模糊综合评判模型,确定了各因素等级标准和权重。鲁班崖滑坡的评价等级为基本稳定,与折线法的结果一致,证明了该方法的可行性,具有一定的理论和现实意义。
Lu Ban Cliff landslide is located in State Road G212 line K365 +832 ~ K366 +140, threatening the safe operation of the national highway. Through field investigation, the structural features, genetic characteristics and trends of the Lubanliya landslide are analyzed in detail. On this basis, taking the formation lithology, geological structure, topography, groundwater and rainfall as the first-class evaluation factors, a fuzzy comprehensive evaluation model of landslide stability assessment is established, and the grade standards and weights of each factor are determined. The evaluation grade of Lubanlian landslide is basically stable, consistent with the result of the polyline method, which proves the feasibility of the method and has certain theoretical and practical significance.
