为了实现对西龙池上水库变形的连续、自动化监测,研制了GPS变形监测软件DDMS,建立了西龙池上水库连续运行监测系统。运行表明,系统具有较高的稳定性,DDMS在观测数据无缺失的情况下,提供有效解的概率高于98%。该软件2h时段解在N、E、U方向的重复性分别为1.2mm、0.9mm、2.2mm,4h时段解算N、E、U方向的重复性为0.8mm、0.7mm、1.5mm。实现了GPS监测系统可进行高效率的实时、自动化、高精度大坝变形监测。
In order to realize the continuous and automatic monitoring of the reservoir deformation in Xilongchi, GPS deformation monitoring software DDMS was developed and a continuous monitoring system of Xilongchi reservoir was established. The operation shows that the system has high stability. DDMS provides more than 98% of the valid solutions in the absence of observed data. The repeatability of this software in the 2h period is N = 0.8mm, 0.7mm, 1.5mm in the N, E, U directions with repeatability of 1.2mm, 0.9mm, 2.2mm and 4h respectively. Realize the GPS monitoring system can be highly efficient real-time, automated, high-precision dam deformation monitoring.
