摘要
总结分析了隧道破碎围岩的力学特性,结合隧道开挖支护施工中容易出现的问题和工作经验,提出了破碎围岩条件下隧道开挖和支护方案的改进意见,以期对同类条件下隧道的施工有借鉴和帮助。
The mechanical properties of crashed wall rock of a tunnel is analysis. According to the problems appeared in the excavation and support of tunnel and experience from the tunneling, the improvement scheme for excavation and support of tunneling in crashed wall rock is proposed, which may be helpful in directing the tunneling in the similar condition.
