摘　　要：以某大坝渗流量分析评价为例,通过引入库水位变化速率这一渗流影响因子,在对库水位变化速率及其对大坝渗流影响进行分析的基础上,研究了综合考虑渗流滞后效应和库水位变化速率影响的大坝渗流统计模型构建原理和方法,并通过与传统统计模型的对比分析,验证了文中方法的可行性和有效性。By taking the analysis and evaluation on the seepage from a dam as a case, the principle and method for establishing the dam seepage statistical model under comprehensive consideration of the hysteresis effect of seepage and the impact from varia- tion rate of reservoir water level are studied herein on the basis of the analysis made on the variation rate of reservoir water level and its impact on the seepage of dam through introducing the variation rate of reservoir water level--a factor of impact on seepage into the study. Furthermore, the feasibility and effectivity of the method given herein are demonstrated through the comparative a- nalysis on the conventional statistic model.
