摘　　要：该文针对标准梯形量水堰在灌区量水中存在的问题,提出改进标准梯形量水堰及其测流公式,并对其进行了试验研究。通过室内试验和对标准梯形堰测流公式的研究分析,得出了改进后梯形量水堰的测流公式;同时,还进行了该量水堰的测流精度分析和原型观测试验,结果表明:改进的梯形量水堰的测流方法及其计算精度完全满足国家农业量水的要求,可以用于田间渠道流量的量测。The standard cipoletti weir and its flow measurement formula were improved aiming at some problems, which existed in the flow measurement of irrigation area. Experimental research of the improved cipoletti weir was carried out. According to the indoor experiments and the analysis of flow measurement formula of the standard cipoletti weir, the flow measurement formula of the improved cipoletti weir was put forward. At the same time, the flow measurement precision and prototype observation experiment were analyzed. The results indicated that flow measurement method and calculation precision were consistent with the rule of country agricultural flow rate measurement, which could be used in the field channel to measure the flow.
