从频率法测索力基本理论出发，归纳总结了边界条件、抗弯刚度以及温度等因素对频率法测试精度的影响。针对自锚式悬索桥短吊索的索力测试，提出了考虑短吊索抗弯刚度和边界条件的频率法实用计算公式。通过现场测试与分析证明，使用该实用计算公式能提高测试精度，可在类似工程索力测试中推广应用。

Based on the basic theory of frequency-method for cable force testing, we summarized the effects of such influence factors as boundary conditions, bending stiffness and temperature exert on the test accuracy. In view of the force test of short ca-ble for self-anchored suspension bridge, we put forward a practical formula for frequency-method considering bending stiffness and boundary condition of short cable. By means of on-site testing and analysis, the results prove that this practical formula can improve test accuracy, which can be applied to cable force testing in similar projects.
