| Abstract: | Based on apparatus of water-air movement,the seepage coefficients obtained from a single sample by changing its moisture and density were compared to that got from samples with different original moisture and density in this paper.The results are almost the same,so the seepage coefficients could been measured on one sample to improve test efficiency. |
