斜拉桥桥索张力测量
Measurement of Cable Tension for Stayed Cable Bridge
【摘要】 本文主要介绍了斜拉桥桥索张力的测量原理,指出了目前人们常用的直接频差法的不足之处,提出了一种确定斜拉桥桥索基频的新方法.后一种方法无论从理论还是从测量上都优于前一种.实测结果证明了这一点.
【Abstract】 Principles for measurement of cable tension based on frequency analysis are discussed. A new method for determining the fundamental frequency of bridge cables is proposed, which is more convenient and accurate in application.
