郧十高速公路某滑坡稳定性分析及治理方案

摘要

The mechanism of Longtoucun landslide at Yunxian-Shiyan Expressway is analyzed consid-ering topographic condition,geological formation,and human engineering activities.Landslide stabili-ty analysis and evaluation are conducted by using the calculation parameters which are determined by experiment,inversion and analogy.The comprehensive treatment measures consisting of changing bridge to road,unloading,interception and drainage are adopted finally.The actual situation shows that the comprehensive treatment measures are attended with good results.%从地形条件、地层岩性、工程活动等方面对郧十高速公路龙头村滑坡的形成机制进行分析；结合试验、反演与类比确定滑坡计算参数，对滑坡进行稳定性分析评价；提出了多种治理方案，经技术经济比选最终采用桥改路、卸载与截排水相结合的综合处治措施。实际情况表明，该综合治理方案效果良好。
