摘要
对山区高速公路不同类型边坡的稳定性受地下水的影响进行分析，从水文地质角度动态判断边坡稳定性并给出针对性的处治建议，同时，采用三维有限差分仿真计算软件FLAC3D，运用强度折减法（strength reduction method，SRM）对G59官新高速沂溪大桥桥下滑坡原因分析及处治措施进行数值模拟并验证其准确性，得出"查明边坡所在微地貌单元的水文地质系统、及时疏通排水通道、避免坡体富水是提高边坡稳定性的重要措施"的结论，以期为山区高速公路设计回溯及边坡设计工作提供参考。
Abstract
In this work， the influence of groundwater on the stability of different types of slopes on mountainous highways was analyzed. The stability of slopes was dynamically judged from a hydrogeological perspective， based on which targeted treatment suggestions were provided. At the same time， the three-dimensional finite difference simulation software FLAC3D was used to numerically simulate the cause analysis and treatment measures of landslides and verify its accuracy under the Yixi Bridge of G59 Guanxin Expressway using the strength reduction method （SRM）. The conclusion is drawn that identifying the hydrogeological system of the micro geomorphic unit where the slope is located， timely clearing drainage channels， and avoiding water enrichment of the slope body are important measures to improve slope stability， providing reference for the retrospective design of mountainous highways and slope design work.关键词
