摘要
对现有拉索线形计算理论进行了研究,系统的给出了不同精度斜拉索线形参数求解公式,计算了梁济运河大桥斜拉索的设计线形,对比分析了其线形参数的精度,得出对于200 m左右跨径的斜拉桥可采用无弹性理论计算斜拉索线形的结论。
The paper researches the calculation theory of the current stay cable, provides the formula of the linear parameter of the stay cables with different accuracies, calculates the design line of the stay cable of the Liangji canal bridge, compares and analyzes the accuracy of the linear parameter, and concludes the stay cable with the span of more than 200 meters can make use of the inelasticity theory to calculate the linear of the stay cable.
