摘要：

An analysis was made of a long-term settlement of the metro line in service for about ten years, 46 joints between the stations and the tunnels in soft soil districts, 34 locations beside the subway connection aisles, and 4 joints between the U-shaped grooves and the tunnels. Analysis results show that about 70% of the settlements occur in tunnel joints rather than in the station joints. The depth and width of settlement groove on the pull-out side are larger than on the pull-in side. About 80 % of differential settlements occur on the railway line beside the subway connection aisles, and about 90% of the differential settlements are settlement groove. The non-uniform settlement at the joint between the U-shaped groove and the tunnel is little.
