隧道工程在施工过程中,一般需要对拱脚进行固定施工,从而提高基地的稳定性。而在实际的施工过程中,采用一般台阶施工法并不能完全保证隧道拱脚的稳定性,特别是在软弱围岩隧道的施工项目中,对于施工的重点更加难以把握,无法有效控制拱脚的稳定性。通过结合实际隧道施工情况,分析了在软弱围岩隧道的施工中,如何采取台阶法提高拱脚的稳定性并对施工质量的控制技术进行简单分析。
Tunnel construction in the construction process, the general need for fixed construction arch foot, thereby enhancing the stability of the base. In the actual construction process, the use of general construction method can not completely guarantee the stability of the tunnel arch, especially in the construction of soft rock tunnel, the construction of the more difficult to grasp the key, can not effectively control the arch foot stability. By combining with the actual tunnel construction situation, this paper analyzes how to take the step method to improve the stability of the arch foot and the simple analysis of the construction quality control technology in the construction of the soft surrounding rock tunnel.
