浅埋大跨暗挖车站隧道施工方案对桥桩的影响

Effects of construction procedure with large span clearance and shallow in city for bridge piles

针对广州小北站复杂的洞群结构和地层关系,文中利用数值模拟的手段进行分析,总结了洞群施工对桥桩的影响规律,通过地下洞室群方案的对比,得到了较为合理的施工方案。

Aiming at complex caves structure and ground layers of Xiaobei station in Guangzhou. Some excavation methods about the station hall whose embedded depth is very shallow were simulated, it sumes up the law of caves construction for bridge piles, by selected the caves construction methods. It gets up the reasonable construction method.
