Abstract

For most soft soil, the consolidation process and the creep process were coupled and the character of settlement time curve was obtained by the consolidation test at the same time. A simple and continuous function was presented 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 were analyzed. The results of the long-term (duration to 18 months) consolidation test on clays from the Chek Lap Kok formation proved the rightness of the method. In the end, the parameter meanings of the continuous function were discussed.
