Evaluation of the Impact of Shield Grinding Pile Crossing River Embankments in the Yangtze River Floodplain Area
In response to the case of shield grinding pile crossing river embankments between Baiyunting Station and Sanchahe.Station on Nanjing Metro Line 9,numerical simulation was used to evaluate the impact of shield grinding pile crossing river embankments,propose refined excavation control measures,compare and analyze the monitoring data of the river embankments after shield tunneling.The results indicate that it is effective to pre-reinforce the river embankment with high-pressure rotating pile,and to propose refined control measures for excavation parameters,excavation volume,and grouting measures during the period of shield grinding pile crossing the river.The maximum settlement is 10.2 mm,and the impact of shield grinding pile crossing on the river embankment is relatively small.
