摘要
朔州隧道是准池铁路最长的隧道,从本隧道的地质条件出发,结合工期等要求,论证了单双线隧道方案、隧道采用TBM掘进机方案及钻爆法方案;并对施工期遇到的进口黄土地层的大变形及侵限进行了原因分析及处理,对上硬下软地层及隧道水平岩层的防塌提出了处理及预防措施,以期给类似工程提供借鉴。
Shuozhou Tunnel is the longest tunnel of the railway from Jungar to Shenchi South. Proceeding from the geolog- ical conditions of the tunnel and combined with the requirements of the project duration, this paper demonstrates the scheme on the tunnel with single track or double track, the plan of TBM adopted in the tunnel and the scheme of drilling-blasting method. And it also analyzes what causes the large deformation of loess stratum at the entrance and its treatments during the construction period, and puts forward the prevention and treatment measures to avoid the collapses of the strata with upper hard and lower soft and the tunnel with horizontal strata, with a view to providing a reference for similar engineering.
