摘　　要：为了维护航道港池泊位水深,每年需要投入大量的经费用于航道疏浚,准确测量水体中含沙量量值,可为港口及航道区域泥沙淤积量的计算、预报和后报提供准确的含沙量测量数据,这对于港口航道维护运营具有重要意义。为了解决水体中含沙量测量的准确性问题,研究了0.1~30 kg/m^(3)范围的含沙量标准场的配制及测试技术,采用烘干称重的方法对该含沙量标准场进行含沙量标准值测试,测试结果显示含沙量标准场均匀度均小于2.88%。提出含沙量测量仪器的校准方法,得到含沙量测量仪器的测量结果相对误差均小于7%。以实例分析了该校准测量结果的不确定度评定方法,实现对含沙量测量仪器的校准能力。In order to maintain the water depth of the berth in the channel and harbor,a large amount of funds are spent on channel dredging every year.Accurately measuring the sediment concentration in water can effectively provide accurate sediment concentration measurement data for the calculation,prediction and post-reporting of sediment deposition in ports and channel areas,which is of great significance for the maintenance and operation of port channel.For the accuracy of sediment concentration measurement in water,the preparation and testing technology of the standard field of sediment concentration in the range of 0.1-30 kg/m^(3)were researched.The drying weighing method was used to measure the standard value of the standard field of sediment concentration.The results show that the uniformity of the standard field of sediment concentration is less than 2.88%.The uncertainty evaluation method of the results was proposed with an instance.The method can calibrate the measuring instrument for sediment concentration,and the relative error of the sediment measurement instrument is less than 7%.
