渗流对深基坑工程的影响研究

Research on influence of seepage on supported deep foundation

依托实际工程,对某河口防潮闸围堰进行了土的渗透特性试验研究,为流固耦合有限元分析提供依据;采用有限元方法进行了数值模拟,研究地下水对深基坑工程的影响,结果表明考虑渗流应力耦合作用的计算结果与实测资料吻合较好,该方法是较为合理的.

Experimentations of soil permeability are taken out, which provides dates for the later calculation, and the influence of groundwater on excavation deep foundation is researched by the FE method, actual observation record coincide well with the FE analysis results which considering groundwater effect,indicating that the method is more reasonable.
