北斗三号高边坡实时监测系统应用研究

针对高速公路建设过程中因线形和环境需要形成的高边坡会产生的边坡失稳进而造成财产损失和人身安全的问题,该文采用BDS与GPS组合定位方法,初步完成高边坡实时监测系统的设计和数据处理。目前,BDS-3系统已经完成基本系统建设,并向全球提供服务。在中国范围内,可观测到的BDS卫星数量较多、质量较好,该文详细分析了BDS-2、BDS-3和GPS在边坡监测中的应用效果。结果表明,该方案能提高定位精度、改善单系统观测条件较差时定位的稳定性和可靠性,在高边坡变形监测中具有重要应用价值。

Research on the application of real-time monitoring system of high slope based on BDS-3

Aiming at the problem of slope instability caused by the high slope formed due to the alignment and environmental needs during the construction of the expressway,which will cause property loss and personal safety,this article used the combined positioning method of BDS and GPS to initially complete the real-time monitoring of the high slope System design and data processing.At present,the BDS-3system has completed the basic system construction and provides services to the world.In China,the number of observable BDS satellites is relatively large and the quality is good.Therefore,this paper analyzed the application effects of BDS-2,BDS-3 and GPS in slope monitoring in detail.The results show that this scheme can improve the positioning accuracy,improve the stability and reliability of positioning when the single-system observation conditions are poor,and it has important application value in the monitoring of high slope deformation.
