摘要:
在繁华市中心修建地铁，越来越多地出现上跨、下穿既有地铁或管廊结构的现象，尤其是与既有地铁车站衔接的换乘车站施工，设计施工难度大。以某地铁换乘车站施工工程为例，介绍了该工程的概况、地质条件和施工特点，对不同的施工方案进行了分析，确定选用全暗挖法施工。并采用数值模拟的方法，对洞桩(PBA)法开挖工序进行比选，以选出最优的施工方案。
Abstracts:
During the construction of metro lines in busy city center, more and more phenomenon of over- or under-passing existing metro or pipe gallery structures is appearing, especially in the construction of transfer stations connected with existing metro stations, of which the design and construction are difficult. Taking the construction project of certain metro transfer station as an example, the background situation, geological condition and construction features of the project are introduced, and different schemes are analyzed. Comprehensive underground excavation is selected for construction. By adopting numerical simulation method, the excavation procedure of PBA (pile-beam-arch) method is comparatively decided as the optimal construction scheme.
