【摘要】：以满足自锚式悬索桥目标成桥状态为前提,针对如何确定自锚式悬索桥体系转换过程中吊索张拉力及张拉程序的问题,提出了自锚式悬索桥体系转换过程的吊索张拉计算方法:调整吊索无应力长度的降温法。由于倒退分析法和传统无应力状态控制法在计算自锚式悬索桥体系转换过程中存在缺陷,在传统无应力状态控制法的基础上,提出了调整吊索无应力长度的降温法。该方法可用于计算自锚式悬索桥且计算方法简单,计算精度高。
[Abstract]:On the premise of satisfying the target state of self-anchored suspension bridge, how to determine the tension of the sling and the stretching program during the system transformation of the self-anchored suspension bridge is discussed. In this paper, the method of sling tension calculation in the process of system transformation of self-anchored suspension bridge is put forward: the cooling method of adjusting the length of sling without stress. The system conversion of self-anchored suspension bridge is calculated by retrogressive analysis method and traditional no-stress state control method. There are defects in the process, Based on the traditional stress-free state control method, a cooling method for adjusting the unstressed length of sling is proposed, which can be used to calculate self-anchored suspension bridge with simple calculation method and high accuracy.
