摘要
根据有限元分析软件Midas Gts NX对临近地铁隧道的深基坑开挖及支护进行数值模拟,分析了基坑开挖对地铁隧道的变形及内力影响,并提出了合理的保护措施,以确保后期地铁运营的安全。
According to the finite element analysis software Midas Gts NX,the excavation and support of the deep foundation pit near the subway tunnel are simulated.The influence of excavation on the deformation and internal force of the subway tunnel is analyzed,and reasonable protective measures are put forward to ensure the safety of the subway operation in the later period.
