摘要
采用荷载结构模型及连续介质力学模型分别对铁路顶桥受下穿地铁区间隧道施工影响所产生的沉降及内力变化进行计算分析 ,并据此提出下穿框架式地道桥的地铁区间的设计及施工的有关技术要求。
Load-structure model and continuous medium mechanical model were used for computational analysis of the settlement and internal force changes of railway bridges due to the construction of metro tunnel under it. And technical requirements were put forward concerning the design and construction of metro sections under a framed underpass bridge.
