摘 要: | 本文通过对重塑土进行同一围压下的K0固结,然后对其进行应力未释放和释放后的不固结不排水试验。试验结果表明,应力未释放的试样强度参数明显高于应力释放后所测强度参数;测定原状土的强度参数时,其先期固结压力的确定是非常有必要的。

Abstract: | Through making K0 consolidation for remoldeds oil,the text does stress release experiments and unconsolidated undrained experiments.The results show that the temples strength parameters which stress unreleased is obviously higher than temples which stress are released.It is necessary and important to determinate pre-consolidation pressure in parameters determination of undisturbed soil. |

Keywords: | K0 consolidation stress release unconsolidated-undrained experiment strength parameters |
