摘要
道路工程会遇到许多路堑边坡,在外部荷载的作用下,路堑边坡容易发生滑坡、坍塌等地质灾害,对公路的运行安全构成了严重的威胁,因此,明确路堑边坡的地质状况与稳定性对于工程设计与施工具有十分重要的意义.采用工程地质调绘、工程钻探、高密度电法等综合方法查明场地条件、岩土层分布规律、岩土层参数,利用 FLAC3D数值模拟软件对某边坡的稳定性进行了数值分析.
Abstract
Many cutting slopes are encountered in road engineering.Under the action of external loads,cutting slopes are prone to geological disasters such as landslide and collapse,which pose a serious threat to the safety of highway operation.Therefore,it is of great significance to clarify the geological condition and stability of cutting slopes for engineering design and construction.The site condition,distribution law of rock and soil layer and parameters of rock and soil layer are ascertained by engineering geological mapping,engineering drilling and high density electrical method.The stability of a slope is numerically analyzed by FLAC3D numerical simulation software.
