| Abstract: | Through summary and evaluation of the experimental investigation on small strain of soil, the paper points out that recent stress history has an important influence on threshold and variation of stiffness within the range of small strain; and it is worth while to further study. Meanwhile, it is also shown that the experimental investigation on small strain could have an active effect on Chinese engineering practice. |

| Keywords: | small strain shear stiffness threshold stress history stress path |
