摘要
深基坑破坏一般常出现在开挖过程中,一旦破坏可能会造成巨大的经济损失和人员伤亡事故,因此,深基坑的开挖和支护一直是工程施工的重点和难点。以某地铁车站深基坑为研究对象,利用PLAXIS有限元分析软件,对基坑开挖和支护的各工况进行数值模拟分析,研究基坑开挖深度、支护结构位移、土体位移等问题。研究表明:PLAXIS能有效地反应基坑围护结构和地面变形规律,并提出控制基坑失稳的方法和建议。
Destruction of deep foundation pits often occurs during excavation.Once the damage may cause huge economic losses and casualties,the excavation and support of deep foundation pits has always been the focus and difficulty of engineering construction.Taking the deep foundation pit of a subway station as the research object,using PLSXIS finite element analysis software,the numerical simulation analysis of various working conditions of foundation pit excavation and support is carried out,and the excavation depth of foundation pit,displacement of supporting structure and soil body are studied.The research indicates that PLAXIS can effectively reflect the foundation pit retaining structure and ground deformation law,and proposes methods and suggestions for controlling the foundation pit instability.
