摘要

In the process of impact coefficient measurement,traditional measurement method has the problems of a large number of sensors,long data transmission cable,complex equipment installation, long bridge closing time.Thus,a method of tast measurement of bridge load impact coefficient based on the technology of wireless mode is put forward.An analysis of the rapid measurement principle and the basic flow of bridge load impact coefficient is made to realize wireless bridge modal technology's rapid measurement of bridge load impact factor.The experiment results show that the improved meth-od can realize quick measurement of bridge load coefficient,and effectively avoid bridges safety acci-dents.%在对冲击系数进行测量过程中，存在传统测量方法传感器数量多、数据传输电缆长、设备安装复杂、桥梁关闭时间长等问题。为此，提出一种基于无线模态技术的桥梁载荷冲击系数快速测量方法。分析桥梁载荷冲击系数快速测量基本原理和基本流程，实现无线模态技术的桥梁载荷冲击系数的快速测量。实验结果表明，改进的无线模态的桥梁载荷冲击系数快速测量方法，可以实现对桥梁载荷系数的快速测量，有效避免桥梁安全事故。
