摘要
测量机器人(即自动电子全站仪)固然可以对大坝进行自动化(或半自动化)外部形变监测,但测量机器人设站 处(监测基点)的稳定性对监测精度的影响非常大,并且当测量视线被遮挡后测量机器人将无法监测相应的形变点,为 了解决上述问题,笔者及科研组将GPS技术与测量机器人技术有机结合,开发出了大坝形变集成监测系统,该系统彻 底解决了监测基站不稳定对监测结果的影响问题,使监测的程序得以简化、监测的固定性投资成本得以降低。文章介 绍了大坝形变集成监测系统的结构、工作原理,给出了监测实例。以实际监测数据为依据,提出了大坝预警的基本准 则。
It is an incontestable conclusion that the Surveying Robot can monitor dams＇ deformation automatically. But the stability of the base point below the Surveying Robot exerts a tremendous influence to monitor precision. The Surveying Robot can not monitor the deformation point, when covering the surveying line with a body. For overcoming the above problem, the integrated monitoring system of dams＂ deformation has been developed. The system is integrated of the GPS technique with Surveying Robot. Using this system, the influence of the stability of the base point to monitor precision has been solved, the monitoring procedure has been simplified, the fixed investment cost of deformation monitoring has been reduced. The structure and work principle of the integrated monitoring system of dams＇ deformation has been introduced. A monitoring example has been given. Based on the field self-inspection data, the basic warning principles of dams have been given.
