基于有限元模拟的边坡稳定性分析
摘要
Abstract
In order to conduct stability analysis on a certain slope and explore the variation law of volumetric strain during the process of slope instability.In this study,the excavation slope of a new water plant in Enshi Prefecture,Hubei Province was selected as the research object,and the FLAC3D calculation model was established.According to the strength reduction method and fish language,the Factor of safety of the excavation slope was calculated,and the change curve of slope volumetric strain in the calculation process was studied.The calculation results show that the excavation slope is in an unstable state after excavation,the Factor of safety is 0.879,the sliding surface runs through the whole slope,and the volumetric strain of the slope decreases first and then increases rapidly during the process of slope instability.In the end of this study,the slope support design of the excavation slope was carried out using the Lizheng Deep Foundation Pit 7.0 and Geo-Studio software.At the same time,the variation of volume strain during the slope instability process is of great significance for monitoring slope instability.关键词
