Abstract: To realize the continuous and automatic monitoring, GPS system is adopted for deformation monitoring of upper reservoir of Xilongchi pumped-storage power station and DDMS software is adopted for processing of monitoring data. The operation shows that the system is of high stability and over 98% efficient solutions rate is achieved by the DDMS in condition of no data missing. For different part, different monitoring periods are set. The plane and elevation results of 2-hour and 4-hour are accurate as required.

摘要: 为实现西龙池抽水蓄能电站上水库表面变形的连续性自动化监测,建立了电站上水库GPS 连续运行监测系统,研制了DDMS 软件进行GPS 变形监测数据的适时处理。实际运行表明,系统具有较高的稳定性;DDMS 软件在观测数据无缺失的情况下,提供有效解的概率高于98%;依据电站不同工程部位观测条件设置的GPS 测量时段,其2 h 和4 h 时段解算的平面、高程成果均能满足监测点设计精度要求,对类似工程高效率实时自动化GPS 变形监测系统的建立具有借鉴意义。
