| Abstract: | The segments from Ranjiaba Station to Dalongshan Station and from Dalongshan Station to Dashiba Station of Chongqing Metro Line 5 are referenced to explain the application of such technologies as grouting reinforcement,synchronous supporting trolley in the lower tunnel and the excavation control of the composite TBM excavation in the upper tunnel of overlapping section based on the characteristics of two overlapping small-spacing tunnels. The results may provide reference for similar works of urban rail transit construction. |
