摘　　要：感潮水闸引水量计算基本采用一潮推流法,但一潮推流法工作量很大,并不适合所有情形的水闸,特别是对于闸门变动较大的水闸,每年需重新校测,测验任务繁重,目前还没有较好的解决方法。以定波闸为例,研究了引水量计算的一种新方法,以水力学公式为基础,分析水位差流量关系,结果表明精度完全达到规范要求。为沿江水闸的引水量统计提供了一个比较精确的简易可行的方法,为精确掌握沿江引水量,实行最严格水资源管理制度提供基础数据。The method of discharge computation for a single tide is generally adopted in the calculation of water di- version amount for tidal sluice. But the method requires long time and large work load. Especially for sluices with changing gates, the measurement and calibration are burdensome. With Dingbo sluice in Wuxi City as a research case, the authors proposed a novel method of calculating the water diversion amount which is based on hydraulic formula to analyze the waterhead-flow relation. Result shows that the calculation accuracy meets the specification requirements. The method is convenient, feasible, and accurate for the statistics of water diversion along the river, and could provide data for the most stringent water resource management regime.
