摘要
根据索的力的平衡条件及变形相容条件, 由缆索无应力长度不变的原则来建立缆索状态方程, 提出了悬索桥主缆空缆状态线形分析的一种新方法. 以虎门悬索桥为例对该方法的正确性和适用性进行验证, 可供桥梁工程技术人员设计参考.
A new method,which is based on the force equilibrium condition and the geometrical compatibility condition of cable,according to the constant unstressed length of cable,is presented in this paper to determinate the geometric of suspension bridge free cable.Numerical examples with Humen suspension bridge are given to demonstrate the effectiveness and the validity of the proposed method.
