| Abstract: | 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 variation 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 analysis on the conventional statistic model. |

| Keywords: | dam seepage monitoring model hysteresis effect variation rate reservoir water level |
