| 摘 要： | 对隧道周围土体采用椭圆形非等量径向位移模式，在镜像法基本原理基础是推导了土体损失引起的附加应力计算公式；结合弹性力学Mindlin解得到的正面附加推力和摩擦力引起的附加应力，得到三者共同作用下总的附加应力公式，并通过算例分析了各影响因素下水平平行隧道上附加荷载的分布规律，重点探讨了土体损失引起的附加荷载在相邻隧道上的分布，分析结果对平行隧道施工具有一定的参考价值。 |

| Abstract: | Based on the theory of image method, the formulas of superimposed stress induced by ground loss are obtained. Combining the formulas of superimposed stress induced both by bulkhead additive thrust and frictional force between shield and soil, which are based on the Mindlin solution, the formulas of total soil stress are obtained. The distributions of superimposed load on parallel tunnel, which are caused by all of the factors, are analyzed by using an analytical calculation case. In the analytical process, the distribution of superimposed load caused by ground loss is discussed emphatically. The result obtained will have some referential value in parallel tunnelling. |
| Keywords: | superimposed load image method ground loss bulkhead additive thrust frictional force |
