地下洞室开挖过程中最难开挖的就是岩体,而在往往的隧道开挖过程中岩体都是不可避免的。能否有效的解决岩体开挖问题直接决定了隧道开挖的成功与否。一旦隧道内部发生坍塌将造成巨大的生命财产损失。有效的保证洞室内围岩的稳定在隧道开挖中占有非常重要的地位。本文主要介绍隧道围岩应力和锚喷支护方法。
The most difficult excavation in the underground cavern is the rock mass, and the rock mass is inevitable in the frequent tunnel excavation. Whether the excavation of rock mass can be effectively solved directly determines the success of tunnel excavation. Once the collapse of the tunnel will result in huge loss of life and property. Effectively guarantee the stability of surrounding rock in the tunnel occupies a very important position in tunnel excavation. This paper mainly introduces the surrounding rock stress and anchor spray support method.
