摘要
为了减少在站驻测成本、解放人力、提高生产效率,本文采用袁家庵站历年实测流量、实测输沙率资料,分析了袁家庵站断面冲淤变化规律、水位流量关系、单断沙关系特性及变化规律,并优化水位、流量、泥沙等测验项目的测验方式。结果表明:站断面冲淤变化较小,历年平均河底高程最大变幅为0.82m,基本稳定;对该站洪水期所定4个单一的水位流量关系曲线分别进行符号检验、适线检验、偏离数值检验,均符合要求,可以应用于生产实际。本文的研究成果可以作为该站和同类站在实行水文巡测时的数据支撑。
In order to reduce the cost in station monitoring,liberate human labor and improve the efficiency of production,based on the measured flow and measured data of sediment discharge of Yuanjia’an Station,the variation law of erosion and silting,the relationship between water level and flow,and the relationship between single fault and sediment in the section of Yuanjia’an Station are analyzed,and the test method for water level,flow,sediment and other test items is optimized.The results show that the erosion and silting of the station section have little variation,and the maximum variation of the average river bottom elevation over the years is 0. 82m,which is basically stable. Four single relationship curves of water level and flow in the flood period of this station are tested by sign test,fit line test and deviation numerical test respectively,which all meet the requirements and could be applied to production practice. The results of this study can be used as the data support of this station and similar stations in the implementation of hydrological survey.
