有轨电车与地铁并行段的暗桥设计研究

Design and Research on Subsurface Bridge in the Parallel Section of Tram and Metro

针对软土地区某新建有轨电车线下结构部分区段与既有运营地铁隧道线路近距离平行的情况,从有轨电车线路的桥式选择,以及桩基施工方法和运营期两者对地铁隧道的影响等方面进行了计算分析,确定了有轨电车的暗桥设计方案及参数。

When the structural section of a new tram line is parallel to the existing subway tunnel line in close distance on soft soil area, the subsurface bridge design and parame- ters of the tram line are to be determined. In the paper, the tram bridge selection and pile construction method are studied, the mutual influences on the metro tunnel during the operation period is analysed, the design scheme and pa- rameters of subsurface bridge are decided.
