斜拉索索力是桥梁施工控制和桥梁受力的重要指标，以光武大桥为工程背景，用频率法进行平行钢绞线斜拉索索力的测试和分析研究。采用有限元方法建立斜拉索模型、HDPE套管模型以及斜拉索-套管整体的接触耦合模型，进行斜拉索结构的动力性能分析，从斜拉索振动频率与索力的对应关系分析可以看出：频率法可用于平行钢绞线斜拉索的索力测试，HDPE套管能够传递和反映内部索体的振动，但必须考虑HDPE套管的影响，根据HDPE套管质量修正斜拉索线密度，提高了斜拉索索力测量和计算的准确度。

The stay cable tension is an important index of construction control and load-carrying capability of ca-ble stayed bridge.The Guangwu bridge is taken as engineering background.The tension measurement of parallel steel stranded wire stay cable was tested and analyzed based on frequency method.The finite element method was utilized to establish the cable model,the HDPE casing model and the contact coupling model of cable and cas-ing.Dynamic performance of the stay cable structure was evaluated.The following conclusions can be obtained from the analysis of corresponding relationship between vibration frequency and cable tension.The frequency method can be adopted to tension measurement of the parallel steel strand wire stay cable.HDPE casing can transfer and reflect the vibration of internal stay cable.But the influence of HDPE casing must be considered. The line density of stay cable should be modified according to the quality of the HDPE casing of cable,which can improve the accuracy of tension measurement and calculation of the stay cable.
