单索面预应力混凝土部分斜拉桥施工控制技术及关键施工工艺的研究

Research on Construction Control Technics and Key Construction Technology in Prestressed Concrete Partial Cable-Stayed Bridges

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 。

With the construction procedures of the two Prestressed Concrete Partial Cable-Stayed Bridges in Changzhou City as a research object, the monitoring and controlling system are established which emphasize mainly on the girder line type control together with the cable force and the grider stress, and the research work for the aspect of the key construction technics of cable-stayed bridge are taken up through the experiment of segment model of bridge tower. Now, these two bridges are connected in high precision with satisfying construction quality and control results.
