摘要
隧道是铁路工程的一个非常重要的部分,但是由于地下水、地应力、地质条件和人为的因素,隧道的施工难度非常大,而地下隧道工程的软弱围岩的稳定性和初期支护不同的方法都已成为隧道施工过程中急需解决的问题。本文通过对隧道施工中所用到的混凝土、钢支撑、钢筋等的作用机理进行分析总结,系统地阐述了隧道初期支护与软弱围岩的作用机理,并且以实例例证两者的应用。
The tunnel is a very important part of the highway engineering, but because of groundwater, ground stress, geological conditions and human factors, the construction of the tunnel is very difficult, and the stability of the weak surrounding rock and initial support of different methods have become a problem in the tunnel construction process.In this paper, the mechanism of action of concrete, steel bracing and reinforcement is analyzed and summarized, and the mechanism of the initial support and weak surrounding rock in tunnel is described.
