基于分段悬链线法,介绍自锚式悬索桥主缆线形计算原理和步骤,考虑弯矩对加劲梁轴向刚度的影响,在迭代计算过程中,提出采用非线性规划方法,并与传统的影响矩阵法进行对比,计算结果表明,两者结果吻合,从而使借助大型通用优化软件对自锚式悬索桥主缆线形进行精确求解成为可能.

In consideration of the effect of the moment on the axial rigidity of the reinforced beam,the theory and practice of main cables configuration calculation of self-anchored suspension bridge were systemically introduced with the method of segmental catenaries.A non-linear programming method was adopted in the iteration computation.The results obtained by the non-linear programming method are in agreement with those by the influence matrix method.Therefore,it would be possible to calculate the main cables configuration of self-anchored suspension bridge by utilizing commercial optimization software.
