以浙江江山北关大桥为工程背景,推导了自锚式悬索桥主缆线形的解析计算方法,通过该计算方法来确定主缆在恒载作用下的几何特征值和内力值,所述的原理和方法对自锚式悬索桥主缆线形的解析计算具有普遍的指导意义。
Taking the Beiguan Bridge in Jiangshan of Zhejiang as the engineering background, the analytical method for calculating the main cable shape of the self-anchored suspension bridge is derived. The geometric eigenvalues and internal forces of the main cable under constant load are determined by this method. Method is of general guiding significance for the analytical calculation of the main cable profile of self-anchored suspension bridges.
