摘要
基于对振频法原理的研究,论述了索力监测系统的硬件结构,上位机和下位机的工作流程,以江津长江大桥体外预应力索为实验对象,采用JMM-268动测仪进行了索力测量,并进行了对比实验,得出该系统满足实际工程需要。
Based on the research of vibration frequency method, the paper discusses the hardware structure of cable force monitoring system, and inquires the working procedure of upper computer and lower computer. Taking external prestressed cable of Yangze bridge in Jiangjin as the ex- perimental target, it measures the cable force with JMM-268 dynamic measurement instrument, and carries out comparative experiment, and final- ly finds out that the system meets actual engineering needs.
