摘要:
南京地铁9号线白云亭站至三汊河站区间盾构磨削穿越秦淮河南岸抗滑桩与堤防，为评估盾构磨桩掘进对秦淮河堤防工程安全的影响，基于Plaxis 3D有限元软件，构建了含抗滑桩堤防及盾构隧道相互作用的精细化三维数值模型，分析不同地层损失率对堤防变形和堤防整体稳定性的影响。研究表明，采取高压旋喷桩补强加固堤防和掘进控制等措施，可将堤顶沉降控制在10 mm以内，堤身安全稳定系数显著提高。
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.
