摘要
对用于桥梁拉索索力测量的4种方法做了讨论,包含压力表读数,压力传感器法,振动频率法和电磁测量法。对这4种方法的基本原理、优缺点做了分析;讨论了磁弹性索力传感器的典型磁路结构及工程应用;指出了索力测量的发展趋势和急需解决的关键问题。
Four stress measurement methods of large bridge cable are discussed, including tension instrument showing, tension sensing measuring, vibrating frequency sensor and electro-magnetic strain sensor. The basic principles, merits and demerits of these four methods are discussed. In addition, both sensor structure of magnetic-elastic stress sensor and real application in bridges are dissertated. Finally, developing trend of cable stress measurement methods and key technologies are proposed.
