| 摘 要： | 针对某地铁叉口变跨度隧道的施工方案进行了离心模型试验 ,模拟了隧道采用双侧壁导坑法施工时地表沉降随各开挖步施工的变化规律 ,同时对相接变跨度隧道施工对地表沉降的相互影响进行了模拟试验 ,试验预测了隧道施工中地表沉降的发生、发展、收敛的全过程 ,所得结果对同类工程具有一定的参考价值

| Abstract: | Through centrifugal model test,this paper simulates the dynamic developing process of the ground surface settlement when the two-side-gallery excavation method is used in variety span tunnel construction,and describes the mutual influence of the ground surface settlement caused by the excavation of the adjacent variety span tunnels.The testing results are of reference value for similar projects. |
