摘要
为适应当前水文现代化发展的要求,探索水文监测改革,本文基于居龙滩水文站历年泥沙颗粒资料,分析了该站测验断面含沙量变化规律,并选取2008—2013年悬移质颗粒级配资料作为样本进行历年单断颗相关关系分析,分析结果符合《河流悬移质泥沙测验规范》(GB/T 50159—2015)精度要求,得出单颗代表断颗进行间测的测验方式可行,对该站优化测验方式,提升监测效率提供了有利的理论支撑。
In order to meet the requirements of current hydrological modernization and explore the reform of hydrological monitoring,based on the sediment particle data of Julongtan Hydrological Station over the years,this paper analyzes the variation law of sediment concentration in the test section of this station,and selects the suspended load particle gradation data from 2008 to 2013 as samples to analyze the correlation of single broken particle over the years.The analysis results meet the precision requirements of Sediment Measurement Specification for Suspended Load of Rivers(GB/T 50159—2015),and draw the following conclusions that the test method of single broken particle is feasible,which provides favorable theoretical support for the station to optimize the test method and improve the monitoring efficiency.
