Abstract: Landslide is a kind of universal and serious geological disaster, which usually has characters suchas high happening frequency、high destroy force and many kinds of destroy performs. In modern highway engineering,because highway is wider and has the higher amount of transport,it has higher demand for the stability of highways slopes.In the paper,taking the XinShaofang landslide in the Highway from Xichang to Muli as example, applying mathematical method of calculation and analysis, the author analyse the developing tendency of the rock and land mass deformation in the course of harnessing landslide. This method is feasible and the analyzing result is prototype to some extend, which have value to analyze the slopes stability and harnessing landslide.?

Key words: landslide, nature status, cutting status, harness status, deformation field, develop

摘要： 以西 (昌 )木 (里 )路新烧房滑坡为例,运用FEM数值计算方法比较详尽地分析了处于天然,开挖及治理状态下滑坡体及邻近岩土体变形场的演绎过程,明晰了滑坡所处岩土环境的变形演绎趋势及过程,与实际情况符 .该方法对于评价、分析滑坡的稳定性态及治理效果具有重要的参考借鉴作用.
