本文在现场调查分析的基础上,基于Midas/GTS的有限元强度折减法对延安市宝塔区卧虎山滑坡进行了数值模拟分析,得出了滑坡的变形情况、滑动趋势以及稳定系数,并把计算结果与传统稳定性计算结果进行了分析比较,证明了基于有限元强度折减法的滑坡稳定性计算方法的可靠性和可行性。
Based on the field investigation and analysis, the Midas / GTS finite element strength reduction method is applied to numerical simulation analysis of the Wohushan Landslide in Baota District, Yan’an City. The landslide deformation, sliding tendency and stability coefficient are obtained. The calculation results are compared with those of the traditional stability calculation, and the reliability and feasibility of the method for calculating the stability of the landslide based on the finite element strength reduction method are proved.
