| 摘 要： | 研究了浅埋隧道周围地层最终变形的计算问题，提出了考虑椭圆化变形影响的计算模型和浅埋隧道位移边界条件，并利用Airy应力函数得到了该问题弹性解析解。在此基础上，通过算例分析了椭圆化变形对竖向位移和水平位移的影响。结果表明，椭圆化变形对水平位移的影响远大于竖向位移。

| Abstract: | The deformation shapes around a tunnel cavity and the elastic solution for the prediction of the tunneling-induced ground deformations for shallow tunnels in the soft ground, are studied. A general ova deformation of ground is suggested and incorporated as the boundary condition of the displacement around the tunnel section. The difference between oval deformation and vertical translation ground deformation patterns on surface settlements and lateral deformation is investigated. The results indicate that oval deformation has a greater effect on lateral deformation than on surface settlements. |

| Keywords: | shallow tunnel settlement lateral displacement oval deformation elasticity analytical solution |
