隧道边仰坡零开挖进洞施工技术探讨

On construction technique for zero excavation tunneling at heading slopes of tunnels

因施工安全及工后环保和山体力学平衡安全的需要,结合工程实际,提出了一种在隧道开挖时不用进行大面积边仰坡削坡来进洞的施工技术,该施工技术能保证安全、快速、环保的进洞。

In order to meet the standards of the construction safety, environmental protection and dynamic balance of mountains, the paper points out the construction technique in the tunnel excavation without adopting the large heading slope tunneling by combining with the engineering facts, so as to ensure the safe, speedy and environment-friendly tunneling.
