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.
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 costly plate loading test is usually used to obtain the load-settlement curve of the pile.
工程上通常是通过静载荷试验来测取桩的荷载-沉降曲线，耗资巨大。
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.
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。
