摘要
以上海浦东国际机场新建长时停车库连接匝道工程为背景,采用MIDAS GTS NX建立三维有限元分析模型,土体采用修正摩尔-库伦模型,研究新建非对称基坑开挖对邻近地铁桩基变形的影响规律。希望研究成果可为该匝道基坑开挖提供参考。
Based on Shanghai Pudong International Airport’s new long-term garage connecting ramp project,a 3 D finite element analysis model has been established using MIDAS GTS NX to study the influence of new asymmetric foundation pit excavation on the deformation of adjacent subway pile foundation. Modified Mohr-Coulomb model is adopted for the soil. I hope the research results can provide a reference for the excavation of this ramp.
