摘要
隧道涌水量预测是确保安全施工的重要环节。以某隧道Ⅳ级围岩段为例,展开了隧道Ⅳ级围岩段涌水预测及注浆加固厚度分析,为隧道施工提供技术支持。
Tunnel inflow forecast is a key link to ensure the safety of the construction. In this paper, an IV-class rock sec- tion of the tunnel is taken for example to conduct the rock section of tunnel Class IV gushing forecast and grouting reinforce- ment thickness analysis so as to provide technical support for the tunnel construction.
