基于数值模拟方法对船山村滑坡流固耦合计算分析

Fluid Structure Coupling Calculation and Analysis of Chuanshan Village Landslide Based on Numerical Simulation Method

摘要: 本文基于实际监测资料及勘查资料，获得拜殿乡船山村滑坡的降雨量、孔隙水压力及土壤含水率的参数，滑坡的变形发展受地下水位波动变化明显，地下水位上升通常是滑坡发生和发展的最重要影响因素，降雨对滑坡的影响主要通过地下水及其渗流场来发生作用。本文采用Geo-studio数值模拟软件，对于降雨条件下该滑坡土壤入渗规律进行模拟，分析滑坡在不同渗流场条件下的稳定性，根据数值模拟结果来判断滑坡发生预警级别。

Abstract: This paper is based on the actual monitoring data and exploration data. The parameters of rainfall, pore water pressure and soil moisture content of Chuanshan village landslide in Baidian township are obtained. The deformation development of landslide is obviously affected by the fluctuation of groundwater level. The rise of groundwater level is usually the most important factor affecting the occurrence and development of landslide. The influence of rainfall on landslide mainly occurs through groundwater and its seepage field. In this paper, geo studio numerical simulation software is used. The soil infiltration law of the landslide under rainfall conditions is simulated. The stability of landslide under different seepage field conditions is analyzed. According to the numerical simulation results, the early warning level of landslide is judged.
