| 摘 要： | 隧道是长输管道工程中一种成本较低的穿跨越形式,但对于岩溶发达地区的大型河流,通江裂缝等地质条件是其主要施工难点.在中石化西南管道广西郁江江底隧道施工中,通过超前探与浅孔探相结合,洞内与洞外预注浆相结合,以堵为主导的治水方式,克服了围岩变形、裂缝涌水、贯通性溶洞等困难,成功打通了岩溶地区第一条小型江底隧道.

| Abstract: | Tunnel is a low cost way for crossing river pipeline projects in longdistance,but crossing river cracks are main difficulties in karst areas.In construction of Yujiang Tunnel in Guangxi in Sinopec Southwest Pipeline,surrounding rock deformation,water-gushing from cracks and through-river caves are overcome by advanced exploration and shallow-bore photograph,combining pre-grouting inside and outside of caves,as well as controlling water by blocking.Thus mini-tunnel in karst riverbed is finished successfully. |
