摘　　要：隧道开挖在软粘土中引起的地层移动对都市环境中的地上建筑物和地下构筑物来说影响很大,因为地基沉降对已有建筑物具有潜在的危险,本文采用有限元法(PLAXIS软件)研究软土地基中单、双隧道施工引起的地基沉降、双隧道埋深、间距变化对地基变形和地面沉降的影响,数值计算结果与其他方法及工程实例的对比。Tunneling- induced soil movement in soft clay is important to underground constructions in populated urban. This is because ground settlement and subsurface movement usually cause potential damage to existing structures. Being different from previous works, this paper focuses on ground settlement and subsurface soil movement of single tunneling and twin parallel tunneling on. the interaction of twin parallel tunneling, burial depth, Relative separation of twin tunnels are numerically studied with geotechnical software PLAXIS. Numerical results are compared with site measurements available and other closed - form solutions.
