Midas-GTS软件在膨胀土滑坡治理工程分析中的应用

Application of Midas-GTS Software in Engineering Treatment Analysis Expansive Soil Slope Sliding

为了评价膨胀土滑坡治理工程,根据工程地质条件、滑坡治理方案及其他相关资料,基于Midas-GTS软件建立膨胀土滑坡治理工程完成三维数值模型,模拟分析滑坡治理完成、治理完成后暴雨工况下边坡稳定性;同时建立该膨胀土滑坡治理工程监测方案,将数值模拟土层的位移场、抗滑桩滑动方向剪力与实际监测结果对比分析。分析表明：治理完成后膨胀土边坡稳定性显著提高,抗滑桩和片石渗沟支护工程对边坡起到支护作用,效果显著。

In order to evaluation of treatment engineering of slope sliding of expansive soil, based on engineering geological condition, slope sliding treatment scheme and other relevant materials, three dimensional numerical model of slope sliding of expansive soil treatment is established. The model simulates the stability of side slope when slope sliding treatment completed and heavy raining. The monitoring scheme of slope sliding of expansive soil treatment is set up. Result compare of calculation and monitoring for soil movement and shear stress is carried out. Analysis results show that the stability of the side slope is raised obviously, and the anti-sliding pile and pie stone support have great effect on side slope support function.
