| 摘 要： | 李家下滑坡是大型岩质滑坡,发育在黄土滑坡众多的黄土高原区。基于野外地质调查、工程地质勘探和室内岩土体分析测试及土工试验,利用Ansys有限元软件对3种气候条件及3种滑带土强度条件下李家下滑坡的稳定性进行了模拟分析。模拟结果表明:滑带土强度参数的改变对李家下滑坡的稳定性有极大的影响,李家下滑坡已处于不稳定状态。结合李家下滑坡最新的变形现象,认为沿主滑带再次滑动的可能性较大。

| Abstract: | Lijiaxia landslide is a large rockslide,encountered in Loess Plateau which is famous for lots of loess landslides.On the basis of field geological survey,exploration of engineering geology,indoor tests of rock and soil mass,simulation calculation with Ansys software were performed on stability of Lijiaxia landslide,considering three kinds of climate conditions and three kinds of strength of slip soil.Numerical simulation shows that variation of strength of slip soil effects stability largely and Lijiaxia landslide is unstable now.The authors think it is probable to slide along main sliding belt,considering the latest deformation of Lijiaxia landslide. |

| Keywords: | Lijiaxia landslide landslide stability strength of slip soil Long County Shaanxi Province |
