摘要
钻爆法建造的常规地质隧道,相对于特殊岩土和不良地质隧道,安全问题原因分析更具有代表性和普遍性,针对钻爆法隧道施工安全,从围岩分级、开挖进尺、围岩排险、初期支护、衬砌步距和施工管理等方面进行隧道掉块、坍塌致因分析,并提出有针对性的对策,对提高隧道掉块、坍塌的安全预防有较强的指导意义。
Drilling blasting method of conventional geological tunnel,relative to special rock soil and bad geological tunnel,safety cause analysis is more representative and universal,in this paper for blasting tunnel construction safety,from surrounding rock grading,excavation footage,rock discharge,initial support,lining stepping distance and construction management,and put forward targeted countermeasures,to improve the tunnel block,collapse safety prevention has strong guiding significance.
