Analysis of stability of Qinhuai River Levee during shield crossing with pile grinding
摘要
Abstract
Shield tunneling in the section from Baiyunting Station to Sanchahe Station of Nanjing Metro Line 9 passes through the anti-slide piles and levee on the south bank of the Qinhuai River with pile grinding.To evaluate the influence of shield pile grinding excavation on the safety of the Qinhuai River levee project,a refined 3D numerical model considering the interaction among the levee with anti-slide piles,strata,and shield tunnel is established using Plaxis 3D finite element software.The effects of different ground loss rates on levee deformation and global stability are analyzed.The results show that by adopting measures such as high pressure jet grouting pile reinforcement and tunneling parameter control,levee crest settlement can be controlled within 10 mm,and the safety stability factor of the levee is significantly improved.关键词
