| 摘 要： | 本文通过对砂土变形的细观分析，讨论了砂土振动蠕变机理，提出了振动蠕变长期强度的概念，认为砂土的振动蠕变长期强度数值上等于其剪胀临界应力，其测试可用静力试验取代费时费力的长期振动蠕变试验，这一结论与试验结果基本一致。

| Abstract: | By meso-analysis of the deformation of sand, this Paper discussses the dynamic creep mechanism of sandand proposes the concept of long-term dynamic creep strength. It is believed that the long-tenn dynamic creepstrength is equal to the critical dilatant stress numerically,and it can be measured by static test instead of the expan-sive dynamic creep test.This conclusion is consistent with test results. |
