随着人们生活水平的提高,车辆的日渐增多,路面交通的压力也越来越大,隧道工程不仅可以有效的缓解交通压力,而且在一些特殊位置能够起到优化路线线形的效果。尤其是近年来随着地铁项目的开展,武汉的隧道工程随处可见,然而伴随而来的是各种大大小小的质量问题和故障,前段时间王家湾地铁修建处的隧道施工就发生了坍塌事故,如何保证隧道工程的质量是当前施工单位最为关注的问题。本文笔者结合自身从事隧道施工的经验,分别从隧道开挖、支护和二衬混凝土三个方面进行了分析,论证了加强对隧道施工工艺的控制对隧道工程的质量有着至关重要的影响。
With the improvement of people’s living standards and the increasing number of vehicles, the pressure of road traffic is also increasing. Tunnel engineering can not only effectively alleviate the traffic pressure, but also can optimize the route alignment in some special places. Especially with the subway project in recent years, Wuhan tunnel project can be seen everywhere, but accompanied by a variety of large and small quality problems and failures, some time ago Wangjiawan Subway Construction Department of the tunnel construction collapse occurred How to ensure the quality of tunnel construction is the most concern of the current construction unit. Based on the experience of tunnel construction, the author analyzes the tunnel excavation, support and the second lining concrete, and demonstrates that the strengthening of the control of the tunnel construction process has a crucial impact on the quality of the tunnel construction.
