| 摘 要： | 借助大型有限元分析软件,对大跨度斜交顶进框架式地道桥底板下开挖地铁对地道桥结构的影响进行较深入的探讨。通过对开挖地铁前、后地道桥受力和变形分析,给出不影响地道桥安全受力状态的地铁开挖最小深度值。

| Abstract: | With the finite element software, the influence on the structure is calculated of metro excavation under large span obliquely intersected framed underpass bridge constructed with jacking method. Based on the stress and deformation analysis of the underpass bridge before and after metro excavation, the value of minimum depth of excavation is presented which has no significant influence on the structure of the underpass bridge. |
