Subsequently, the influences of stress level and stress history on the secondary consolidation coefficient are discussed.
当处于正常固结状态时，次固结系数近似为一常数。
In normal consolidation state the coefficient remains approximately a constant value.
而当超载预压处理后，次固结系数随超载比和超载作用时间不同而变化。
But when surcharge preloaded, the coefficient will change with the overload ratio and its duration time.
这些参数包括压缩指数、回弹指数、次固结系数、初始再固结体积压缩系数等。
Theses parameters include compression index, expansion index, coefficient of secondary consolidation and initial coefficient of re consolidation volume compressibility, et al.
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。
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.
