Based on the model, the secondary compression settlement formula is established, which reflects the influence of soft clay characteristics, pre-consolidation pressure and reloading pressure.
根据次固结系数双曲线模型建立的次压缩变形计算公式，既反应了软土本身性质的影响，也反应了预固结压力和再加荷压力的影响。
The secondary consolidation coefficient is not related to time of sustained loads, and it becomes larger as the reloading pressure increases and becomes less with the pre-consolidation pressure.
试验结果表明：随着固结压力的变化，压实黄土的次固结系数表现出与当前应力状态有关的变化规律。
