摘　　要：润扬大桥结构健康监测系统中的整体变形监测采用美国GPS全球卫星定位系统,主要用于监测悬索桥桥身和桥塔的结构位移。为解决GPS的RTK短期失锁问题,提高监测可靠度和精度,在润扬大桥GPS监测系统升级中,采用GPS+北斗的新监测方法 ,文章介绍了GPS+北斗监测系统的工作原理,并对其精度进行验证,结果表明,GPS与北斗卫星导航系统的联合使用提高了解算成功率,解决了RTK失锁问题。Global Positioning System （GPS） is instrumented in structural health monitoring （SHM） system of Runyang Bridge, which monitors displacements of girder and tower of the suspension bridge. During upgrading of GPS monitoring system in Runyang Bridge, GPS＋ Beidou technique is adopted to overcome loss of lock in RTK technique and improve the monitoring reliability and precision. This paper introduces working principle of GPS＋Beidou monitoring system. And the reliability and precision of the new method is verified through monitoring data.
