以常州两座单索面预应力混凝土部分斜拉桥的施工过程为研究对象 ,建立了以主梁线形控制为主且兼顾斜拉索索力、主梁应力的控制体系 ,并通过索塔足尺节段模型试验等工作对部分斜拉桥关键性施工工艺开展研究。目前两桥均已高精度合拢 ,取得了满意的施工质量和控制结果
The construction process of two prestressed concrete cable-stayed bridges with single cable plane in Changzhou is taken as the research object. The control system with the main girder linear control and the stress of both the main cable and the cable is established. Section model test work on some of the key construction technology of cable-stayed bridge to carry out research. At present, both bridges have been closed with high accuracy and achieved satisfactory construction quality and control results
