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.
