本文给出了软土地层中浅埋和深埋隧道开挖引起的地表变形的弹性理论解。将隧道断面周围的椭圆形地表变形模式作为隧道断面周围位移的边界条件。研究了均匀径向和椭圆形地面变形模式在地表和地下沉降及侧向变形方面的差异。五个案例研究被用来检查所提出的分析解决方案的适用性。一般来说，预测的地面变形与均匀粘土中隧道的现场观测结果吻合良好。
This paper presents the elastic solutions for the prediction of the tunneling-induced ground deformations for shallow and deep tunnels in the soft ground. The oval-shaped ground deformation pattern is incorporated as the boundary condition of the displacement around the tunnel section. The difference between uniform radial and oval-shaped ground deformation patterns on surface and subsurface settlements and lateral deformation is investigated. Five case studies are used to check the applicability of the proposed analytical solutions. Generally the good agreement of the predicted ground deformations can be seen with field observations for tunnels in uniform clay.
