摘　　要：对振动法测试斜拉桥索力的若干问题诸如拉索边界条件、抗弯刚度、垂度、测试系统的分析精度等因素对索力测试精度的影响进行了比较详尽的分析,并提出了实际的解决方法,对斜拉桥施工具有一定的指导意义。This paper analyzes in considerable details several problems in connection with cable force measurement of cable-stayed bridges with vibration measurement method, such as the influences of the boundary conditions, bending stiffness, sagging of the stay cables, and accuracy of measurement instrument on the cable force measurement accuracy, and provides practical solutions to the problems in the measurement. The analysis and solutions in the paper are of certain guidance to the construction of the cable-stayed bridges.
