摘　　要：本文将GPS全球定位系统中的单频差分GPS定位技术和数字超声波测深仪SDH-13结合起来,并通过导航软件将平面数据和水深数据进行匹配,对水电站库区淤积进行实时动态测量,大大地提高测量精度和工作效率。同时,本研究根据库容计算的模型和误差传播理论,提出了一种河道型水库库容计算成果的精度评价方法。最后,本研究成果在安康水电站库区测量的应用表明,本研究提出的方法能经济可靠地完成水电站库区淤积测量任务。This system combines single frequency differences GPS positioning technology of GPS with digital ultrasonic echo-sounder SDH-13 and matches plane data with depth data by the navigation software, carrying out real-time kinetic measurement on hydropower station reservoir area deposits, which improves the accuracy and efficiency of measurement greatly. At the same time, according to the reservoir storage calculative model and error spread theory, this study has explored a kind of accurate valuation method of river-like reservoir storage on calculating achievement. And the successful application in the measurement of reservoir area in Ankang hydropower station indicates that the achievement can make reservoir deposit of hydropower station be measured economically and reliably.
