摘要
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。
Lubanya Landslide is located at K365+832~K366+140 of National Highway G212,which threats to safety operation of the national road.A detailed analysis of the structure features,causes and activities trend of Lubanya Landslide through field survey is mades.On this basis,a landslide stability evaluation model is established based on fuzzy math.Lithology,geological structure,topography,groundwater and rainfall are evaluation factors in the model.The classification standard and weight each factor are determined.Evaluation result of Lubanya Landslide is stable,which is consistent with evaluation result of Line method.The result demonstrates that the method is feasible.So,the model has some theoretical and practical significance.
