摘要
基于频谱法原理对斜拉索进行索力测试,针对斜拉索索力测试中的拉索抗弯刚度、边界条件、垂度影响、温度影响进行了定性和定量分析并给出了实测中采用的对应措施,最后结合涪陵乌江二桥索力测试中提出了测试拉索索力的方法,实际证明该方法是有效的.
Vibration theory is employed in a cable tension test in this paper. Qualitative and quantltatwe analysis are carried out concerning its flexural rigidity, boundary condition, sag effect and temperature effect, Finally, taking the example of Wu Jiang second bridge cable tension test, test method is put forward and proved effective,
