| 摘 要： | 固结试验的一般数学描述是建立在主次固结人为的分开的基础上的.而本文根据固结试验所得到的沉降与时间关系曲线的特点,建立了一个简单实用且连续的函数来描述固结试验,并分析了该模型的特点.历时18个月的香港软土固结试验,验证了该方法的正确性,并对模型的参数进行了讨论. |

| Abstract: | Based on the assumption that between the primary consolidation and the secondary consolidation is segregated artificially, piecewise analytic functions are used to express the primary consolidation stage and the secondary consolidation stage respectively. However, Due to the character of settlement time curve obtained by the consolidation test, the paper presents a simple and continuous function to express the whole process of consolidation including immediate settlement stage, the primary consolidation stage and the secondary consolidation stage. And the features of the continuous function are analyzed. Then the results of the long-term (durations to 18 months) consolidation test on clays from the Chek Lap Kok formation prove the rightness of the method. In the end, the parameter meanings of the continuous function are discussed. |
