粉砂土质地铁车站深基坑支护有限元模拟分析

Finite Element Simulation Analysis on Deep Foundation Pit Support of Subway Station with Silt Soil

应用ANSYS有限元软件,模拟文汇路地铁车站明挖深基坑支护中土体和支护结构的应变和位移,选择了合理的支护结构和土体的有限元设计参数,分析了基坑可能产生的变形与破坏形式。通过实际施工监测结果,验证了有限元模拟的设计参数的合理性,提出了设计与施工中应采取的应对措施。

The deep foundation pit of the wenhui rod subway station was simulated by the element software of ANSYS to get the displacement and strain of the soil and supporting structure. The reasonable finite element design parameters of the supporting structure and the soil are chose, and the potential deformation and failure mode of the pit are analyzed. In addition, based on the actual construction monitoring results, the reasonableness of the design parameters of the finite element simulation is verified, and the response measures for the design and construction are put forward.
