摘要
以郑州地铁1号线新郑州大学站1号、2号出入口通道为工程实例,通过理论计算了暗挖通道上覆松动土压力,研究结果表明:郑州地铁采用CRD法浅埋暗挖小导管超前注浆能够大幅度减小上覆松动土压力,进而验证了该方法用于郑州地铁出入口施工的可行性,论文为该方法在郑州地铁的后续施工和设计提供了参考。
The 1 st and 2nd access passages in new Zhengzhou University station of No. 1 subway line of Zhengzhou City are taken as engineering examples, the overlying loose earth pressure on the access passage tunnel are theoretically calculated, and the results reveal that CRD method and small pipe grouting method in shallow buried tunneling can obviously reduce the overlying loose earth pressure, and so these methods are proved to be feasible for the access passage tunnel construction in Zhengzhou Subway, and this paper can provide reference for the construction and design for the access passage tunnel construction in Zhengzhou in future.
