| 摘 要： | 为准确模拟斜拉桥成桥索力分布,在斜拉桥索力模拟常规迭代法的基础上,从迭代初值的选取和迭代加速的超松弛法两方面实现了迭代计算的加速.提出了成桥线形修正的建模坐标迭代法,与迭代加速法共同应用于斜拉桥的初始平衡构形的建立.该方法建立的初始平衡构形快速准确的模拟了斜拉桥的索力分布和戍桥线形,能够作为后续分析的起始状态.通过对斜...

| Abstract: | To obtain the accurate simulation of the cable force distribution of cable-stayed bridge,based on the general iteration methods of cable force simulation,a method for accelerating iteration was obtained from the two aspects including the selection of initial values and over-relaxation iterative method.The modeling coordinate iteration method for bridge curve-shape correction was given,and this method was successfully applied in company with the accelerated iteration method in the modeling of initial equilib... |
