Abstract:

Daheiting reservoir has been in operation for more than 40 years. The total seepage in main dam foundation is obtained from the sum of regional seepage in dam gallery. Because the dam seepage is relatively scattered, the total seepage can't be obtained by regional monitoring points. Therefore, the existing monitoring data can not exactly reflect the total seepage, which affects the analysis of seepage data. To solve this problem, the total seepage in dam foundation can be obtained by monitoring the water level change in water collecting wells and the amount of water forcibly discharged from water collecting wells to downstream, which meets the monitoring requirements and improves the project management level.

Key words: safety monitoring, total seepage, monitoring system

摘要:

大黑汀水库已建成运行40多年,主坝坝基总渗流量由坝体廊道内分区渗流量求和得到。由于坝体内渗流 较分散,分区监测点未能监测到全部渗流量,因此现有监测数据不能完全反映坝基总渗流量,影响渗流量监测数 据分析。为解决该问题,监测了坝体内集水井水位变化和集水井强制排向下游水量,求得了坝基总渗流量,满足 监测要求,提高了工程管理水平。
