| 摘 要： | 以贵州境在建杭瑞高速公路某大型滑坡作为研究对象,在综合分析已有的工程地质勘探资料的基础上,对滑坡产生的原因进行了剖析。同时运用极限平衡法,分析了滑坡变形破坏的模式及滑坡稳定性,提出了强支挡、削坡减载+抗滑桩及全削坡减载等3种滑坡治理措施。在此基础上对不同整治措施的技术可行性及经济指标进行比较分析,优选削坡减载+抗滑桩方案。实践表明,削坡减载+抗滑桩方案是一种治理滑坡性价比很好的方法。

| Abstract: | Taking a landslide of Hangzhou-Ruili Expressway in Guizhou Province as a study object,on the basis of comprehensive analysis of existing engineering geological exploration data,the causes of the landslide are studied,and the deformation failure modes and stability of the landslide are analyzed by the using of limit equilibrium method.Then three landslide treatment measures that consist of the heavy support structure、cutting-slope unloading+anti-slide piles and all cutting-slope unloading are put forward.On such a basis,the technical feasibility and economic indicators of different control measures is compared and analyzed.Ctting-slope unloading+anti-slide pile is optimized to dealing with landslide and is proved to be an effective method. |
