摘　　要：为探讨基于红外光技术的悬移质泥沙在线监测系统在宜昌水文站的适用性,在宜昌水文站测验河段进行了TES-91含沙量在线监测系统比测试验。利用监测值与传统人工测验含沙量数据,分析该泥沙监测仪的适用范围和使用条件。分析结果表明:该系统在宜昌水文站有一定的适用性;在线监测泥沙与人工实测断面平均含沙量相关系数为0.99;泥沙监测仪在低含沙量水域的量程范围内(0.002~0.235 kg/m3)具有较好的稳定性,且精度满足要求,在现代泥沙测验中具有很好的应用推广价值。In order to discuss the applicability of the online monitoring system of suspended sediment based on infrared technology in Yichang Hydrological Station, the comparison test of TES-91 online monitoring system of sediment concentration is conducted in the test section of Yichang Hydrological Station. The application range and conditions of the sediment monitor are analyzed by the monitoring value and the sediment concentration data of traditional manual test. The analysis results show that the system has certain applicability in Yichang Hydrological Station. The correlation coefficient between online monitoring sediment and artificial measured cross-section average sediment concentration is 0.99. The sediment monitor has good stability in the range of low sediment concentration waters (0.002~0.235 kg/m3), and the accuracy meets the requirements, which has certain application and promotion value in modern sediment testing.
