摘要
本文以虹桥某地块项目为例,结合围护设计方案,建立了基坑开挖的三维有限元数值模型。首先,将模型计算所得位移与启明星设计软件计算位移进行比较验证;其次,利用验证后的模型对各工况下水库的变形及内力变化规律进行模拟分析。实例分析结果表明,本次模型计算结果与启明星计算结果较吻合,可用于评价围护方案中保护措施对水库泵站的保护效果。
For the project of Hongqiao, according to the Pit supporting scheme, a Three-dimen- sional finite element numerical model of deep excavation was established. First, the computed result of numerical model was compared with the computed result of the phosphor foundation pit. Secondly, the deformation and internal force variation law was been simulated by using validated model. The results of engineering example showed that the computed result of numerical model were consistent with the phosphor foundation pit. And it can be used to evaluate the protective effect of protection measures on the reservoir pump station in the envelope plan.
