摘　　要： 结合现场测试工作,对频率法测量索力的理论与技术应用于张弦式桁架索力的测试进行了探讨.测试结果表明边界条件为铰支并考虑刚度影响的计算公式与实际索力较为接近.频率法测量索力可作为张弦式桁架施工中索力的监控手段. Based on the measurement, the problem of the cable force survey on the truss-string structure is explored by using the theory and technology of measuring frequency. The result indicates that the formula that border confining is articulate and stiffness influence is taken into account is close to the actual situation. The method of measuring cable force by means of frequency is suitable for monitoring the work on the building of truss-string structure.
