苏州火车站改造工程盖挖逆作法施工技术

On the construction technique of the cover and excavation top-down method in the reconstruction project for Suzhou railway station

介绍了苏州火车站改造工程在低渗透性、饱和、软流塑的软弱地层中采用盖挖逆作法修筑地铁车站的施工技术,指出在地铁车站施工中,盖挖逆作法对工程环境影响较小,工期短,综合技术经济指标较为理想,可推广应用。

The paper introduces the construction technique, the cover and excavation top-down method, which is adopted in the construction project of the subway station in the weak strata featured with low permeability, saturated and soft flowage plastic in the reconstruction project for Suzhou railway station, and Imints out in the construction of the subway station, the cover and excavation top-down method, which has little influence on the construction environment, has shorter construction period and ideal comprehensive technical and economic index, so it can be further extended.
