摘　　要：通过对桥梁结构静动力特性及墩台沉降等观测,并结合桥梁常规检测方法,对大跨径预应力混凝土连续刚构桥洛溪大桥因终止收费而引起交通量骤增进行了全天候实时安全监测。结果表明桥梁终止收费前后结构静动力特性未有实质性改变,监测是成功的。Incorporated with regular inspection, a 24-hour real-time safety monitoring of structural static and dynamic characteristics, pier settlement, etc., is conducted on Luoxi Bridge,a large span PC bridge of continuous rigid structure, on which the traffic volume has increased rapidly since the toll was cancelled. The results show that the structural static and dynamic characteristics of the bridge have not been changed substantially, and the monitoring is successful.
