滑坡稳定性三维数值模拟分析

滑坡作为地壳表层的三维地质体,应最大程度逼近实际边界条件评价其稳定状态,同时,由于滑坡不同部位结构构造存在差异,应用不同的稳定系数评价其不同部位的稳定状态。在滑坡稳定性分析方法研究现状对比分析的基础上,介绍一种简易实用而精确度又较高的滑坡稳定性三维数值模拟分析方法,正是为达到此目标的一种探索,分析结果与已有研究成果基本一致,证明这种分析方法具有一定的可信性和优越性。

ANALYSIS ON LANDSLIDE STABILITY BY USING THREE-DIMENSIONAL NUMERICAL SIMULATION

The stability of landslide which is taken as three dimensional geological body in the surface of crust should be evaluated in terms of its actual boundaries as far as possible with different stable coefficients at different parts of landslide due to its various constitute and structure in space.On the basis of contrast analysis of research level of landslide stability assessment,we try to introduce an easy and practicable method with high precision for landslide stability analysis by using three dimensional numerical simulation to approach the aims.The analysis results are consistent with the previous related research results,and it proves that the methodology has some reliability and superiority.
