基于北斗的大坝连续压实监控系统研究及应用

针对目前在大坝碾压施工过程中,传统施工质量控制方式难以满足日益提高的对高坝施工技术的需要,基于北斗卫星导航系统(BDS)和地理信息系统(GIS),对大坝碾压施工质量实时监控技术进行研究。通过安装在碾压机械上的加载设备及振动传感器采集数据,在集成软件处理并记录该碾压机械碾压施工过程,实现对碾压过程全程、全自动的实时监控。将研究结果应用于平桥水库面板堆石坝碾压施工过程中,结果表明,系统实现了对大坝碾压施工过程压实质量参数的有效监控,为大坝高质量、高强度施工提供保障,为工程管理提供便利和依据。

Research and Application of Continuous Compaction Monitoring System Based on BDS

In order to solve problem of traditional construction quality control method could not enough to meet increasing demand for high dam construction technology in dam rolling construction process at present.Real-time monitoring technology of dam rolling construction quality based on Beidou Navigation Satellite System（BDS）and Geographic Information System（GIS）was studied.Data was collected by loading equipment and vibration sensors installed on rolling machine，and integrated software was used to process and record rolling construction process of rolling machine to realize full-time and fully automatic real-time monitoring of rolling process.Study results were applied to roller compaction construction of Pingqiao Reservoir face rockfill dam.Application results showed that system could effectively monitor compaction quality parameters during rolling construction process，which could provide guarantee for high quality and high strength construction of dam and provide convenience and basis for project management.
