摘要
苏州轨道交通4号线Ⅳ-TS-05标观前街站及观—乐区间部分结构位于复杂地下人防的下方,其中地下连续墙、抗拔桩(立柱桩)、降水井、钻孔咬合桩等施工均需竖向穿过地下人防,施工难度极大,施工风险非常高。为此,专门开展了轨道交通基坑穿越复杂地下人防时的地层变形控制研究,为工程施工提供技术指导,同时亦为今后类似工程提供成功范例和可借鉴的经验。
Part of the structure of Guanqian Street Station and Guan Le interval of IV-TS-05 bid section of Suzhou Rail Transit Line 4 structure lies below the complex underground civil air defense. However, the construction of underground diaphragm wall, uplift piles (column piles), dewateri ng well, bored secant piles, etc. shall be con ducted vertically through the underground civil air defense. So the construction is extremely difficult and the construction risk is very high. For this reason, the study on stratum deformation control of rail transit foundation pit vertically through complex underground civil air defense is specially carried out to provide technical guidanee for engineering construction, while at the same time to provide successful examples and referential experienee for similar projects in the future.
