摘要
以某邻近地铁结构的深基坑工程为例,采用等效刚度法将围护桩等效为地下连续墙建立有限元模型对基坑地下水渗流过程进行了三维数值分析,分析了基坑地下水渗流对邻近地铁结构影响,提出了优化改进措施以减小地下水渗流影响,对于指导工程实践有一定意义。
This paper took the deep using the method of equivalent stiffness, wall to build the finite element model and foundation pit of an adjacent subway structure as an example, the fender pile was equivalent to the underground continuous three dimensional numerical analysis of groundwater seepage in foundation pit is carried out, analysis the impact of groundwater seepage pit on adjacent subway structure. The optimization and improvement measures are put forward to reduce the influence of groundwater seepage, which is of some significance in guiding engineering practice.
