摘要
为科学合理地在坝上水文断面开展悬移质颗粒级配测验,更好地收集相关水文资料,根据1956~2019年连续64年含沙量资料及1970~2019年连续50年粒径资料,分析了流域泥沙变化趋势,开展了受水利工程影响的坝上站悬移质颗粒级配测验方式优化分析工作,制定完善的测验优化方案,可保证在新水沙特性下水文资料收集的代表性和精度的同时减轻测验工作量。
In order to conduct a scientific and reasonable test of suspended sediment particle distribution at the hydrological section above the dam and collect better hydrological data,the variation trend of sediment in the basin was analyzed based on the sediment concentration data of 64 years from 1956 to 2019 and particle size data of 50 years from 1970 to 2019.The optimization and analysis of the test method for particle grading of suspended mass on dam stations affected by water conservancy projects are carried out,and a perfect test optimization scheme is formulated,which can ensure the representativeness and precision of hydrological data collection under the new water-sediment characteristics and reduce the test workload.
