摘要
文中阐述了在软岩隧洞施工中一些常见的方法及施工中改进的方法经验,经反复试验此项做法,能有效控制软岩隧洞的岩体坍塌。与中腔注浆锚杆比较,既省时又省费用、而且施工简单容易操控。
The paper elaborates some common methods and improved method experiences in construction of soft rock tunnel.Through repeated tests of the improved method,the results show that the rock collapse of the soft rock tunnel could be controlled effectively by using the improved method.Comparing with the hollow grouting anchor,the improved method has the advantage of saving time and cost,the construction is simple and easy to operation.
