摘要
为精确掌握佛子岭、磨子潭、白莲崖三座水库自建设以来库容的动态变化情况,采用卫星定位技术精确获取控制点坐标,利用机载激光雷达和多波束测深系统对水上、水下地形进行全覆盖测量.结果表明:三座水库受泥沙淤积等因素影响,现库容相较于库容批复值明显减少;在水库运行管理工作中须有序开展清淤工作,保障其防洪、灌溉、供水及生态维护等综合功能的正常发挥.该技术测量数据准确、全面,测量成果可为水库安全评估、防洪调度等提供参考与借鉴.
Abstract
To accurately monitor the dynamic changes in the reservoir capacity of the Foziling,Mozitan,and Bailianya reser-voirs since their construction,satellite positioning technology was used to precisely obtain control point coordinates.An airborne lidar and mul-tibeam sonar system were employed to conduct full coverage measurements of both the water surface and under-water topography.The results showed that the three reservoirs were affected by sediment accumulation and other factors,and the current storage capacity was significantly reduced compared with the approved value of storage capacity.In the operation and management of reservoirs,it was necessary to carry out dredging work in an orderly manner to ensure the normal perfor-mance of its comprehensive functions such as flood control,irrigation,water supply and ecological maintenance.The measure-ment data of this technology were accurate and comprehensive,and the measurement results can provide reference for reservoir safety assessment and flood control operation.
