摘要
以某二级公路新团滑坡为研究对象,深入分析该滑坡形成的地质背景及其基本特征,并对其地层岩性、构造、自重应力等工程地质条件进行综合分析,总体定性评价该滑坡为不稳定滑坡;通过采用极限平衡法和Flac3D数值模拟计算两种方法进行比较,在天然和暴雨状态下,探讨在其数值存在差异的情况下,却能得出相同结论的因素,为此类滑坡定性评价提供一个较好的方法.
In this paper,Xintuan of secondary roads landslide for the study,in-depth analysis of geological backgroundand the basic characteristics of the landslide,and its engineering geological conditions under the comprehensiveanalysis of lithology,structure,stress weight,overall qualitative assessment of the landslide unstable landslide,werecarried out. We calculated by the two methods of limit equilibrium method and numerical simulation Flac3 D usingthe comparison,and heavy rain in the natural state,to explore differences in the presence of its value. But it can cometo the same conclusion of factors,such as qualitative evaluation of landslide provide a better approach.
