摘要
依据监测深基坑支护结构的建筑物沉降、水平位移、支撑轴力等,对开挖支护施工安全性进行了有限元分析,探讨了结构整体及细部的最大位移及弯矩等形变性质。将支护方案进行比选,建立了有限元三维模型,对深基坑的开挖过程做了进一步的施工三维模拟。结果表明,该深基坑支护体系的基坑形变控制实施方案可行,安全施工得到了保障。
According to the monitoring on building subsidence,horizontal displacement,strut axial forces,and so on of deep foundation pit supporting structure,the finite element analysis on the safety of the excavation support construction has been carried out,the maximal displacement and bending moment and deformation properties of the overall structure and details are discussed.The comparison on support plan is carried out,and a finite element three-dimensional model is established for three-dimensional simulation of further construction of the deep foundation pit excavation process.The results show that the excavation deformation control scheme of the deep foundation pit supporting system is feasible,and the safety construction is guaranteed.
