邻近建筑物暗挖地铁车站采用洞桩法的技术探讨

An Exploration of Using Hole Pile Method for Sub-surface Excavation of Metro Station Adjacent to Existing Buildings

在介绍洞桩法施工技术概况的基础上 ,采用二维有限元计算模拟 ,分析洞桩法各主要阶段结构和地层变形过程。论证邻近建筑物暗挖地铁车站 ,采用洞桩法施工的安全及稳定性较好 ,能够有效保护邻近建筑物。

An introduction is given to hole pile construction method, and based upon which, an analysis was made of each phase of the method, and stratum deformation process during construction. The method was proved safe and reliable when used for subsurface metro station adjacent to existing buildings.
