摘要
从内因和外因两方面分析了隧道出现塌方的原因,通过对爆破方案的选择、控制开挖及加强初期支护、仰拱及衬砌、监控量测等措施进行具体阐述,总结了软岩隧道开挖过程中预防塌方的经验,以期指导实践。
From both internal and external aspects to analyze causes of tunnel collapse,through specific description on the measures,such as the choice of blasting program,control excavation and strengthening initial support,invert and lining,monitoring and measuring etc.,it summarizes the experiences to prevent tunnel collapse during soft rock excavation,so as to guide practice.
