摘要
以重庆某区间隧道工程开挖施工为例,重点介绍了在不同围岩级别中,小净距隧道采用的开挖施工方法、施工工序、特殊情况的处理,从而满足小净距隧道中夹岩层及隧道回填埋深层的稳定,确保隧道施工安全。
With an intersection tunnel excavation construction in Chongqing as example, the excavation construction method adopted in differ- ent adjacent rock grade and small distance tunnel and its construction procedure, special situation treatment were introduce critically therefore satisfied small distance tunnel inter space rock and tunnel backfill embedded depth stability, and guaranteed tunnel construction safety.
