摘　　要：安康水电站库区自蓄水以来已运行15年,由于泥沙淤积等原因,无法确定目前的实际库容。本文将GPS全球定位系统中的差分GPS定位技术和数字超声波测深仪SDH-13结合起来,通过导航软件将平面数据和水深数据进行匹配,对安康水电站库区淤积进行实时动态测量。结果表明:经过15年运行,安康水电站库区正常蓄水位330 m以下库容损失2.728×108 m^3(损失率10.55%),其中死库容损失1.945×108 m^3,占总库容损失的71.3%。The reservoir in Ankang Hydropower Station has operated for 15 years since it stores water. On account of sediment deposition, real reservoir capacity can not be learned. Combining differential CPS and SDH-13 digital ultrasonic depth sounder, real-time dynamic survey of the sediment deposition in the reservoir for Ankang Hydropower Station is realized by matching panel data and water depth data using navigator software. The results showed that after 15 years running, reservoir capacity loses 0.2728 billion m^3 below the normal pool level of 330 m, the loss rate is 10.55%. Dead capacity loses 0.1945 billion m^3, accounting for 71.3% of general reservoir capacity loss.
