| 摘 要： | 以成都市清水河桥施工为背景,对自锚式悬索桥施工过程中的主缆线形进行了计算监控。根据解析法理论编制的主缆位移程序,计算得出施工误差和主缆线形变化的关系式,并利用MIDAS6.7软件模拟了不同轮次吊索张拉对主缆位移的影响规律。通过计算数据与主缆施工的实测值进行对比分析,证明了主缆线形变化规律的正确性,可以满足施工和设计要求。

| Abstract: | Taking the construction of Qingshuihe Bridge as background,computer monitoring is carried out on the main cable shape of self-anchored suspension bridge in construction.With the main cable movement programme compiled by analytical theory,the equation between construction error and main cable shape change is calculated and MIDAS6.7 is used to simulate the effect pattern of suspension cable tension on main cable displacement.Comparison between the calculation data and moni-tored value show the correctness of main cable shape change pattern and it can meet the construction and design requirement. |
