摘要
随着大断面隧道的普遍和超大断面的出现,在软弱破碎的围岩中如何确保该类隧道安全、快速施工变得尤为重要。本文对软弱围岩大断面隧道常用的几种开挖方式进行了分析比较,为在实际工程中选择更有效的施工技术提供了理论支持。
With the widespread large cross section tunnel and the emergence of super large cross section. How to ensure that in the weak broken surrounding rock the tunnel safety and fast construction is particularly important. In this paper, the commonly used several kinds of large cross- section tunnel in weak rock excavation method has carried on the analysis and comparison,to choose the more effective in the actual engineering construction technology provides the theory support.
