摘　　要：以重庆地铁 24 号线区间下穿渔溪河段建设为背景,为了降低下穿河流施工风险,采用超前地质预报的方法结合地质材料和工程资料综合了解掌子面前方的地质情况,并制定下穿渔溪河综合施工方案,在区间隧道浅埋段下穿河道时,上游修建围堰配钢制排水管进行引水,对区间正线上方范围内的水进行抽排,提供作业条件,保证了工程整体安全可控。Taking the construction of Chongqing Metro Line 24 under the section of Yuxi River as the background,in order to reduce the risk of construction under the river,the method of advanced geological forecasting combined with geological materials and engineering data is adopted to comprehensively understand the geological conditions in front of Zhangziqian,and formulate the following In the comprehensive construction plan for Chuanyuxi River,when the shallow buried section of the tunnel crosses the river,cofferdams are built upstream and steel drainage pipes are used to divert water,and the water in the range above the main line of the section is pumped and drained to provide operating conditions and ensure The overall safety of the project is controllable.
