摘　　要：首先引出在大型桥梁上开展强震观测应用的重要性,进而介绍在珠江黄埔大桥上布设强震动监测和警报系统的设计思路和方案,最后介绍系统使用的预期效果,达到桥梁震动报警、损伤判定、模态参数更新、时程数据捕获分析等目的。It raises the importance of developing the strong earthquake monitoring application on large bridges in this article at first, then the design ideas and scheme of laying strong earth- quake monitoring and warning system of Huangpu Bridge over Zhujiang River are expoun- ded. And the expect of using system that achieved the purpose of alarming bridge vibration, damaging judge, renewing modal parameters, captured and analyzing time-histories data are introduced at last.
