0.引言:隧道施工中,因为岩体是隧道结构体系中的主要承载结构,所以隧道施工中围岩的稳定和减少对围岩的扰动,避免过度破坏岩体的强度非常重要,因此在施工中应选择适当的施工方法。一、隧道开挖1.洞口开挖。洞口工程是整个隧道施工的控制工程,因此在洞口开挖时应确保洞口的稳定和安全,先根据地质资料控制好边坡和仰坡的高度及坡面长度,做好边坡的稳定工作。
0. Introduction: In tunnel construction, because the rock mass is the main bearing structure in the tunnel structural system, it is very important to stabilize the surrounding rock and reduce the disturbance to the surrounding rock in the tunnel construction so as to avoid over-destroying the strength of the rock mass. Therefore, Should choose the appropriate construction methods. First, the tunnel excavation 1 hole excavation. The hole mouth project is the control project of the entire tunnel construction. Therefore, the stability and safety of the hole should be ensured in the excavation of the hole. The height and the slope length of the slope and the back slope should be controlled according to the geological data, and the slope stability should be well done.
