应用 GEO软件通过数值模拟方法研究地下水、降雨以及地震等环境因素对边坡稳定性的影响，结果表明：当地下水位在滑移面以下时，孔隙水压力和渗透力对边坡稳定性的影响较小，反之则影响较大；随着降雨强度的增加，边坡水平及竖向有效应力呈减小趋势，降雨强度、降雨持续时间的增加导致边坡稳定性降低；当降雨强度小于土壤的入渗能力，降雨完全入渗时，边坡的稳定安全系数主要受降雨强度的影响；地震作用下产生的超孔隙水压力引起边坡的有效应力明显减少，在地下水位较高时减少幅度可达到50%。基于模拟分析结果，针对路基边坡失稳多发的问题，对边坡治理技术及其适用性进行了系统总结分析。

T he effect of groundw ater,rainfall and earthquake on the slope stability w as analyzed based on the mathematical simulation with GEO . T he results revealed that the pore water pressure and the penetration had little influence on the slope stability w hen the groundw ater level w as low er than the sliding plane,and it turned to the opposite when the groundwater was higher. W ith the increase of rainfall intensity,the horizontal and vertical effective stress in the slope w as reduced. Rainfall of higher intensity and longer duration resulted in the decrease of slope stability. W hen the soil has a higher penetration and rainfall fully seep into the ground,the stability factor of the slope was mainly influenced by the rainfall intensity. Extra pore water pressure caused by earthquake resulted in the decrease of effective stress significantly; even 50% if the groundwater level was relatively high. Based on the simulation,the slope treatment measurement and its applicability were systematically analyzed and discussed.
