基坑开挖过程围护结构稳定性分析与应用

The stability analysis and application on retaining structure in foundation pit excavation process

由于苏州火车站基坑开挖面积与深度较大,为确保施工安全,通过ANSYS有限元软件计算对围护结构在开挖过程各阶段基坑稳定性进行了评价,并通过计算分析结果,得知钢结构支撑能有效地减小墙体应力应变,作用明显,从而制定了基坑开挖的具体施工方法与支撑施工要求。

Due to the foundation pit big excavation area and greater depth of Suzhou railway station, in order to ensure the construction safety, through the ANSYS finite element software calculation made evaluation to each stage foundation pit stability of retaining structure in excavation process, and through the calculation and analysis results, gained the steel structure supporting could effectively reduce the wall stress and strain, the effect obvious, so as to formulate the specific eonstruction method and supporting construction requirements of foundation pit excavation.
