水库库岸滑坡稳定性研究

Study on stability of landside of reservoir area

以清江水库库岸台子上滑坡为例,在滑坡影响因素的敏感性分析的基础上对滑坡成因进行了研究,并从滑坡可靠度计算和深部位移监测成果分析等方面对滑坡稳定性进行了研究,分析认为,滑带抗剪强度参数、地下水位对滑坡稳定安全系数的影响较为敏感;滑坡稳定性可靠度值为1.64;深部位移监测资料有利于对滑坡体稳定性作出比较客观准确的评价。因此,对台子上滑坡进行适当的工程治理是十分必要的。

On the basis of studying the sensitivity and the mechanism of Taizhishang landslide, this article analyzes the displacement monitoring result and the reliability of the landslide to discuss the stability of the landslide. The strength parameter and the underground water level are very sensitive to the safety factor of the landslide. The reliability of the landslide is 1.64. And the safety monitoring result of deep displacement could help us to evaluate the stability of the landslide according to the current situation of the landslide. Based on the above analysis, this article pointed out that it's very necessary to treat the landslide.
