某自锚式悬索桥吊索张拉施工控制技术探讨

Study of Construction Control of Suspendertension of Self-anchored Suspension Bridge

以某自锚式悬索桥为例,对自锚式悬索桥吊索安装顺序、张拉过程进行研究,针对自锚式悬索桥在各施工阶段中吊索的张拉力大小、次序、调索次数及相关的控制因素作深入探讨。并进行建模分析,根据实际施工的阶段,应用现有的大型有限元软件MIDAS6.7进行模拟、计算。

Taking a self-anchored suspension bridge as an example, cable installation sequence and tension process for the self-anchored suspension bridge are studied. In various stages in constructing the self -anchored suspension bridge, the ten-sion force and sequence, times of adjusting cable forces and re-lated control factors of the cable are studied in detail, then the bridge is modeled and analyzed by MIDAS6. 7 simulation soft-ware based on actual construction stages.
