摘要
针对某电站上库坝在初蓄期的渗流性态进行分析,以总结初蓄期渗流规律。通过在坝体不同位置布置不同监测仪器对大坝进行监测,以相互验证监测结果的准确性。渗流监测资料显示该面板坝渗流量小于设计允许渗漏量。部分部位坝基渗压水位较高基本与库水位同升同降,坝基可能存在裂隙与库内水位相关。
In this paper,seepage behavior of upper reservoir dam of a power plant during initial storage period is analyzed to summarize seepage law during initial storage period.Dams are monitored by different monitoring instruments arranged at different locations of the dam body to verify the accuracy of monitoring results.The seepage monitoring data show that the seepage flow of the panel dam is less than the design allowable seepage.Seepage water level of dam foundation in some parts is higher and basically rises and decreases with reservoir water level.Cracks in the dam foundation may be related to the water level in the reservoir.
