强风化千枚岩高边坡稳定性分析与治理研究

Study on the stability evaluation and treatment mesaure of high and steep slope with strong weathering phyllite

以206国道寻乌段强风化千枚岩高陡边坡滑坡稳定性研究为基础,通过对滑坡坡体结构及变形破裂特征进行分析,并对该滑坡稳定性作出正确评价。重点研究了该滑坡的滑带土的力学性质特征,利用参数分析结果对滑坡稳定性进行定量分析验算,计算出该滑坡安全系数取1.3的情况下的剩余下滑力,提出滑坡治理对策。

Study on the stability evaluation and treatment mesaure of lhigh and steep slope with strong weathering phyllite in Xunwu segment of National Highway 206,the characteristics of the deformation and the geological structure are analyzed.Based on the study and analysis,the evaluation of the stability is provided.The mechanical characteristics of the landslide are the important factors when the slope is analyzed.According to the analyzed data of the stability,the remaining declined force is calculated at the FS=1.3 and the treatment measures are provided.
