Abstract: Seepage monitoring is important for dams. Combination of water measuring weir and monitoring instruments is mainly adopted worldwide, which is more applicable to the cases when the flow is greater than 1 L/s, while its effect is not ideal when the flow is less than 1 L/s. Combined with the application of tipping bucket flowmeter in the automatic seepage flow monitoring system of Jicun dam, the application scenario, function principle, installation and debugging, and daily operation of tipping bucket flowmeter at measuring points with small flow are described, worth reference.

Key words: dam safety monitoring, automated system, small flow monitoring, tipping bucket flowmeter

摘要： 渗流量监测是重要的大坝监测项目，国内外主流采用量水堰配仪器监测，主要适用流量大于1 L/s的情况，在小于1 L/s的小流量情况下应用效果不理想。结合翻斗式流量计在纪村大坝渗流量监测自动化系统中的应用，阐述小流量测点采用翻斗式流量计的适用场合、功能原理、安装调试及日常运行等情况，为其他大坝相关监测提供参考。
