摘要
针对航道系杆拱桥拆除施工时不能中断通航和系梁等构件中含有强大预应力的特点,采用贝雷导梁支架预留通航孔和特定预应力释放程序进行拆除施工,取得了良好的效果,为类似工程提供借鉴。
As normal navigation has to be secured and large prestress in the components such as the fled beam will be released during the demolishing of the tied arch bridge above water channel, Bailey nose girder and bracket is used to preset navigation hole and to make prestress released. The demolishing engineering has achieved fine result and can be consulted by similar engineering project.
