M型连拱隧道的一种施工工法

A consruction method of M-style twin tunnel

结合实际工程施工经验,提出新奥法原理在M型连拱隧道施工中的应用主要体现在其施工为动态施工,对新奥法原理在M型连拱隧道的洞身开挖、洞身支护和衬砌等施工技术问题上进行了分析,介绍了防排水处理、监测和所采用的安全措施,实践证明M型连拱隧道施工的工法是安全可行的。

Based on construction experieces, the characteristics of the construction method of M-style twin tunnel by the use of Xin＇ao method embodied in its dynamics. The application of the Xin＇ao method on the drying method, supporting and protecting measure, lining and drainage of the tunnel were also provided. The drainage,monitoring and surveying method, and the safety measures emplored in the construction were briefly introduced too. Construction experiences show that the method mentioned in the paper is safe and feasible.
