| 摘 要： | 为了研究软土的蠕变固结特性，进行了一维的固结蠕变压缩试验。得到了连云港软土的蠕变特性。以参数Cα/?e100分析了次固结对固结过程的影响。把饱和粘性土骨架视为粘弹性体，提出了一种划分主次固结的方法，并且，此方法可以应用于实测资料进行主次固结划分。

| Abstract: | In order to study the creep properties of soft soil, a 1-D consolidation–creep test has been completed. The creep properties are summed up from the test results. The effect of the secondary consolidation on the consolidation process is analyzed by the parameter Cα/Δe100 Taking the saturated soft clay as viscoelastic body, a new method of separation of the secondary consolidation and primary consolidation is proposed. The method can also be used by the data collected at the field. Some interesting conclusions concerning the effect of secondary consolidation are drawn from the test results. |
