摘要
联络通道施工是盾构隧道施工中的事故多发阶段,如何选择合理的周边土体加固方式是保证联络通道施工安全的关键环节。本文介绍了联络通道的结构形式和常见的施工方法,详细比较了各种加固方式的利弊。结合苏州地铁一号线各个联络通道所处地层情况,给出了各个联络通道拟采用的加固方式。实践证明采用水平冻结加固方式,可以保证联络通道施工的安全。最后给出了几点体会与建议。
The cross-passage construction is an accident-prone phase in the construction of shield tunnel and how to select the surrounding soil reinforcement methods is the key to ensure the cross-passage construction safety. This paper presented the structure and common construction methods of cross-passage,and gave a detailed comparison of the pros and cons among various reinforcement methods. Combining with the stratigraphy of each cross-passage in Suzhou subway line 1, this paper put forward the proposed reinforcement methods of each cross-passage. The practice showed that horizontal freezen reinforcement method can ensure the safety of the cross-passage construction and some experiences and recommendations are suggested in the end.
