摘要
结合某矮塔斜拉桥实际工程,叙述了斜拉索的张拉控制内容及注意事项,提出了用最小二乘法计算斜拉索拉力和频率之间的函数关系,并验证了其可行性,同时分析了斜拉索拉力随工程进度的变化规律。
In combination with an actual project of a low pylon cable-stayed bridge ,the tensioning control project was described, it was proposed to use the least square method to calculate the function relationship between the tensioning force and frequency of the stay cable, and its feasibility is verified. Furthermore, the changing rule of the stay cable tensioning force with the construction schedule was analyzed.
