摘要: 软弱围岩的力学特征及其变形规律是实现软弱围岩隧道安全快速施工的理论基础。强度低、变形大、变形时间长、变形速度快是软弱围岩的基本特征,因此在软弱围岩隧道施工过程中,必须根据围岩应力调整的特征及其变形规律,合理选择开挖分部和开挖进尺,切实做好超前支护,加强施工管理,按照“预支护、快挖、快支、快封闭”的施工原则,实现软弱围岩隧道安全快速施工。

Abstract: Safe and rapid construction technologies for weak surrounding rock tunnels must be based on the mechanical characteristics and deformation laws of weak rock. Low strength, large deformation, long deformation course and rapid deformation velocity are the basic features of weak rock. For safe and rapid construction, excavation subdivision and footage should be selected according to the mechanical characteristics and deformation laws of weak rock. Advanced supporting for rock in front of the excavation face should be carried out according to the fact, and the construction principle of "advanced support, rapid excavation, rapid support, rapid closure" for weak surrounding rock tunnels should be observed in the construction of weak surrounding rock tunnels. 

Key words: tunnels, weak rock, mechanical characteristic, deformation laws, safe and rapid construction
