长江三峡库区巴东县黄土坡滑坡稳态分析及防滑措施

为了防止长江三峡库区巴东县黄土坡整体失稳，分析了多种因素对滑坡稳定性的影响，并用SARMA法对滑体稳定性进行了计算分析，考虑了滑体不同部位的岩体构成，并和有限元计算结果进行了比较，在分析、计算、判断的基础上，得出结论；在久雨暴雨的情况下，只有防止大气降水和人类排水渗入地下，才能预防滑体大规模失稳，并根据黄土坡的地形条件，提出若干改善滑坡体稳定性的工程措施。

Stability Analysis of Huangtupo Sliding Land at Badong Town in Yangzhi River Three Gorges and the Prevent Sliding Measure Cai Yongsheng1 Zheng Jianfang2

In order to prevent a great sliding of the Huangtupo sliding land at the Badong town in Yangzhi River Three Gorges, the effect of multiple factor on the stability of the sliding land is analyzed. The stability analysis is worked out by means of SARMA method with consideration of complicated rock formation, and is compared with the FEM analysis result.On the bases of theory analysis, calculation and character judgement,it is concluded that in the case of lasting raining and storm,the sliding land will remain stable only if the surface water doesn't seep into the ground. Some engineering measures to improve the stability according to the terrain character are proposed.
