Study on Deformation Control of Metro Shield Existing Railway Passing Underneath in Ancient River Sediment Area |
| |
| Abstract: | Aiming at the shield construction through the existing railway in the ancient river channel sedimentary area of the south extension project section 2 of Shanghai Rail Transit Line 9, i.e. from Songjiang South Railway Station to Zuibaichi Station section, Experimental research was carried out for the measures of railway track pre-reinforcement, simulation crossing, muck improvement, shield construction parameter control, secondary grouting and layered grouting reinforcement and adding polymer injection device to guarantee the shield successfully passed through the railway. |
