摘　　要：轨道交通线路工程大多在小交路站设置折返线、停车线。当小交路站与接轨站距离大于10km时,还需增设停车线。分析研究了含折返线、停车线车站的配线区暗挖法施工的适用性,并进行了明、暗挖法造价比较;配线区机械暗挖法可优化全线配线设置,以增加配线设计的灵活性,减小车站明挖法施工规模和管线搬迁量,节省造价及工期。Most rail transit projects set turn-back tracks and stabling tracks at stations on the short-turning route.When the distance between the station on the short turning route and the junction station is greater than 10 km,additional stabling tracks are also required.The applicability of the mining method to construct the siding area of stations with turn-back tracks and stabling tracks is analyzed and studied,and a cost comparison between the cut and cover method and the mining method is carried out.The construction of the siding area by the mechanical mining method can optimize the siding option,increase design fexibility,reduce construction scale and pipeline relocation works,and save costs and schedules.
