| 摘 要： | 采用统计回归方法对坝基渗透压力监测资料进行分析,结合渗压水位历时过程线资料,探讨了水位、降雨量、坝基排水以及时效等因素对渗压的影响。探求三板溪水电站坝基渗压的变化规律及发展趋势,准确全面地对大坝坝基渗压状况做出评价。结果表明:坝基渗透压力受库水位影响较为敏感,随库水位的升高而增大;渗透压力变化呈现靠近岸坡侧断面大、中间河床断面小的特点。

| Abstract: | We use regression analysis method to analyze the permeability pressure monitoring data of dam foundation of Sanbanxi Hydropower Station.Combining with diachronic curves of permeability pressure level,we discuss influential factors of permeability pressure such as water level,precipitation,drainage in dam foundation and aging.The changing regularity and developments of permeability pressure at dam foundation are explored to evaluate the permeability pressure condition correctly and comprehensively.The result... |
