随着工程建设的加多,在工程遇到的问题也越来越多,比如在公路、铁路的建设中对隧道的一些施工中遇到麻烦。隧道里经常会遇到浅埋地层,比较松散、软弱,围岩比较破碎等等一系列的不完整的地质带,在施工时候无疑给施工设计人员增加了难度,对隧道施工变形和对其稳定性的控制中很难把握,没有处理好,就很容易造成坍塌等安全事故,本文主要是针对隧道软弱围岩初支变形的成因进行分析,具体的应对策略和造成坍塌时的应急措施,如何预防安全问题的发生进行探讨。
With the increase of engineering construction, more and more problems have been encountered in the project. For example, some problems in tunnel construction have been encountered in the construction of highways and railways. The tunnels often encounter a series of incomplete geological belts of shallow buried strata, relatively loose, weak, surrounding rock and so on, which will undoubtedly increase the difficulty for construction designers in the construction period, and reduce the deformation and stability of the tunnel construction Sex control is difficult to grasp, if not handled well, it is easy to cause collapse and other safety accidents. This paper mainly analyzes the causes of the initial branch deformation of soft surrounding rocks in tunnels, how to deal with them and how to deal with the emergency measures in collapse. Prevention of the occurrence of safety issues to be explored.
