叶家坡滑坡治理方案设计

The Design of YeJiapo Landslide Treatment Scheme

以叶家坡滑坡为研究对象,通过资料收集、野外勘探、室内试验等工作,系统地分析了滑坡特征,对滑坡在天然状态、饱水状态、地震状态下的稳定性进行了计算,得出了稳定性结论,提出了滑坡治理方案。该滑坡的治理方案是在综合考虑技术、安全、施工等各方面因素,经过方案对比后决定的。对于次级滑坡断面(上部)采用抗滑桩的治理方案。对于次级滑坡断面(下部)采用削方的治理方案。并且在适当的位置设置排水沟和截水沟。

On the basis of data collection ,field exploration ,laboratory tests and so on ,Ye Jiapo landslide is researched .This article uses Ye Jia po Landslide as the object of study .Through data collection ,field explo-ration ,laboratory work ,this article systematically analyses the feature of landslides .Then ,calculate the stabil-ity coefficients of the landslide in the natural state ,water-saturated state and seismic state .Stability conclu-sions are reached ,and the landslide control scheme isdesigned .The treatment scheme of the landslide is chosen from different programs ,taking account of the technical ,security ,construction factors .The final decision is that ,for secondary landslide cross section (upper) ,the treatmentchooses anti-sliding piles .For landslide sec-tion of secondary (lower) cut isthe governance program .And in the proper position set drainage and intercep-ting drain .
