盾构机在始发和到达掘进过程中,可能由于端头地层的不稳定造成突水、涌砂等较大风险,因此需要对端头进行加固。本文以某工程为例,首先分析其所在地质和水文地质后,然后针对工程实际情况分析加固方法后决定使用WSS注浆工艺,最后对工程加固范围和WSS注浆工艺进行探讨,从而为类似工程提供借鉴参考。 Shield machine in the starting and reaching the tunneling process may be due to the instability of the terminal formation caused by water inrush, sand and so a greater risk, so the need to reinforce the terminal. Taking a project as an example, firstly, after analyzing the geology and hydrogeology in which it is located, the WSS grouting process is decided after the reinforcement method is analyzed according to the actual situation of the project. Finally, the reinforcement range of the project and the grouting process of WSS are discussed, Provide reference for reference
