Abstract: Daheiting reservoir has been in operation for over 30 years. Partition seepage of the main dam foundation was monitored by measuring weir. Artificial observation was carried out by reading of the scale installed on the side wall of the canal at the weir, which contained large error and exerted harmful influence on data analysis. Research on reading instrument was conducted. The new design not only solved the original problems, but also eliminated the difficulty in artificial observation. Further, it has been well proved in everyday use that it meets the requirements of monitoring and improves the management level.

摘要： 大黑汀水库已建成运行30多年，主坝坝基分区渗流量采用量水堰进行监测，人工观测项目通过安装在量水堰处引水渠边墙上的读数标尺读取堰上水位，误差较大，影响坝体渗流量监测数据分析。通过对量水堰人工读数仪的研究设计，不仅解决了原来存在的问题，大大降低了人工观测难度，且在日常应用中得到了很好的验证，满足了监测要求，提高了工程管理水平。
