摘要
东山供水工程的9号隧洞全长22.64km,其中土洞长2.3km,岩石洞长20.34km,隧洞地形条件复杂,施工支洞布置难度较大,通过比较分析,确定合理的施工方法,即土洞段采用钻爆法施工,岩石洞段采用隧洞掘进机施工。
In Dongshan Water Supply Project,the total length of NO.9 tunnel is 22.64 km,in which,the length of soil tunnel is 2.3 km,and the length of rock tunnel is 20.34 km.The tunnel＇s topographical condition is complex,to set up construction drifts is difficult.By means of comparing and selecting alternative plans,the reasonable construction methods are determined： drill-blast tunneling method is adopted in soil tunnel section,TBM tunneling method in rock tunnel section.
