| Abstract: |
| In this paper, the sense of study of seepage and the methods of experiment are explained. According to the experiment results of two kinds of conditions, the relationship curves of stress axis strain, relative water head~ratio of maximum main stress difference as well as relative water head~angle of internal friction are obtained, The effects of seepage on shear strength are obvious and the results of the two kinds of conditions are different. |
| Key words: seepage,shear strength,relative water head,ratio of maximum main stress difference,axis strain |
