摘要
本文对采用频率法测定斜拉桥索力时的若干问题诸如索的刚度、垂度、边界条件以及加装减振器等因素对索力测试精度的影响进行了比较详尽的分析。结果表明，只要斜拉索的计算长度被合理确定，则根据所测频率基于弦振动原理所获的索力在一般情况下均具有相当的精度，可以满足斜拉桥施工控制的需要。
Such factors as stiffness, initial shape, boundary conditions and vibrationreducer of cable which have influence on the test precision of cable tension in cable-stayedbridges by frequency method have been analysised in this paper. The results demonstratethat test precision of cable tension determined by frequency method based on priciple of vibration of chord can meets the needs of construction control of cable-stayed bridges if calculation longth of cable has been determined rationally according to themethods given inthis paper.
