摘要
GNSS监测系统经过多年发展已具有较高的定位精度,在国内水利工程中也有应用,特别是北斗三号卫星导航系统的建成开通,使我国的全域定位精度有了很大提升。为适应新时代水利行业发展要求,实现高精度、全天候动态监测,百色水利枢纽在安全监测系统升级改造中,首次采用了GNSS外部变形自动化监测系统。文章介绍了百色水利枢纽厂房边坡、副坝和汪甸防护堤外部变形监测系统的基本原理、监测内容、建设方式和运行结果,供其他工程在外部变形监测改造或设计中参考借鉴。
GNSS monitoring system has a high positioning accuracy after many years of development, which has been applied in domestic water conservancy project, especially the opening of the Beidou-3 navigation satellite system, which has made the whole positioning precision improved greatly. In order to adapt to the development requirements of the water conservancy industry in the new era and realize high-precision and all-weather dynamic monitoring, Baise Water Conservancy Project adopts GNSS external deformation automatic monitoring system for the first time in the upgrading of the safety monitoring system. This paper introduces the basic principle, monitoring content, construction mode and operation results of the external deformation monitoring system for the plant slope, secondary dam and Wangdian protective dike of Baise Hydropower Station, which can be used as reference for other projects in external deformation monitoring and transformation or design.
