摘要
根据花凉亭土坝1991～2003年的渗流观测资料,分析了坝体和坝基测压管水位的变化规律和变化趋势及其与各影响分量的关系,建立了管水位的统计模型和回归模型,定量研究了上游水位、下游水位、降雨量、时效分量的影响,综合评价了大坝的渗流性态。
According to the seepage observation data on Hualingting earth dam during 1991～2003, analysis is made of the changing law and tendency of piezometric level in dam body and foundation, as well as their relationship with various influencing factors. The statistic model and regression models of piezometric level are established to analyze the effects of upstream water level, downstream water level, precipitation and the time-effect factor in quantitative method. Based on this a comprehensive evaluation of seepage flow state of dam is made.
