天津铜锣湾广场深基坑开挖流固耦合分析

Coupled fluid-mechanical analysis of deep excavation for Tianjin causeway bay plaza

通过对天津铜锣湾广场深基坑开挖过程的流固耦合分析,揭示了主、被动土压力和孔隙水压力的分布规律,探讨了开挖前期降水对土体变形的影响,验证了该深基坑工程设计的合理性。所得结论,对类似工程有重要的理论指导意义和借鉴价值。

Numerical analysis for deep excavation in Tongluowan Square of Tianjin has been done according to coupled fluid-mechanical theorem. In this way, the general rules of soil pressure and pore water pressure were proposed. This paper also discusses the relationship between prior dewatering and soil movement. Based on the analysis, the feasibility of excavation design is evaluated. Some conclusions obtained are useful for the future construction and other structure designs.
