Abstract: Automatic seepage monitoring is carried out by application of measuring weir, which is suitable for the situation where seepage more than 1 L/s and in proper place only. This paper advanced the method to perform automatic seepage monitoring in situation of less seepage and with nonstandard measuring weir. Its application at Zhexi hydropower station showed it was of good effect and expanded its application range.

摘要: 当前大坝渗流量自动化监测一般结合量水堰进行,根据现有技术标准,量水堰自动化监测适用于渗流量大于1 L/s的情况,且量水堰标准结构对场地有一定要求,限制了渗流量自动化监测的应用范围。本文提出了在小流量及非标准量水堰情况下的渗流量自动化监测方法,并成功应用于柘溪水电厂坝基渗流量监测,拓展了渗流量自动化监测应用范围。
