增加曲线模型自身的特点，决定了它能很好地拟合一级荷载下的地基沉降-时间曲线，这已得到了验证。
The logistic curve model can well simulate the settlement-time curve of foundation under uni-level loading with its own virtues, which has been validated by others.
大量工程实践验证表明，无论是一级荷载还是多级荷载下的指数曲线模型，均可对地基沉降进行较好地预测，但也存在不足之处。
Lots of engineering examples show that the exponential curve models, for either single-stage loading or multi-stage loadings, can well predict foundation settlement, but they have shortcomings.
快速荷载试验与常规载荷试验最大的不同是：常规载荷试验每一级载荷作用下的沉降达到了相对稳定状态，而快速载荷试验下的沉降则处于一种非稳定状态。
The most important difference between the slow test and fast load test is, in the former, the settlement under each load reaches to a state of steady, while it is unsteady in the latter test.
