贝雷钢便桥在城市轨道中的应用

Application of Steel Bridge in Urban Rail

城市建设发展速度飞快,城市老城区构建筑物进行着迅速更新。城市地铁盾构区间部分需要穿越既有桥梁,若桥梁桩基础侵入区间隧道,在盾构穿越前需要对老桥梁拆除和桩基拔除,在原有桥梁位置新建桥梁避开盾构区间,桥梁拆除前,在桥梁附件搭设一座钢便桥确保交通通畅。文章对贝雷钢便桥验算及搭设进行了详细阐述。

City construction development speed quickly, the old city city building structure with rapid update.
