摘　　要：通过对长喉槽量水堰在疏勒河双墩子断面和玉门关断面的实地观测与深入分析,运用Winflume软件进行建模和率定,建立了水位与流量之间的关系。结果表明:长喉槽量水堰在不同条件下均能够取得出色的测流效果,表现出卓越的可靠性和准确性。通过对1号和4号长喉槽的流量曲线和流量表进行详尽分析,验证其在设计流量范围内的普适性,1号长喉槽设计流量0~31.7 m^(3)/s范围内均适用,4号长喉槽设计流量0~34.5 m^(3)/s范围内水位流量关系同样适用。研究结果为疏勒河流域长喉槽量水堰提供技术支撑。This paper presents the field observation and in-depth analysis of the long throat flume weir in Shuangdunzi section and Yumenguan section of Shule River.The Winflume software was used for modeling and calibration to establish the relationship between water level and discharge.The results show that the long-throat flume measuring weir can achieve excellent flow measurement effect under different conditions,showing excellent reliability and accuracy.Through a detailed analysis of the flow curve and flow meter of 1#and 4#long throat grooves,the universality of the design flow range is verified.The design flow of 1#long throat groove is applicable in the range of 0~31.7 m³/s,and the design flow of 4#long throat groove is also applicable in the range of 0~34.5 m³/s.The research results provide technical support for the long-throat flume weir in the Shule River Basin.
