摘要
通过用MMF曲线拟合模型对地基土体固结过程中土体固结沉降量与固结时间之间的关系进行拟合,得到了各时刻比较准确的固结沉降速率,进而利用上述线性关系计算了土体的固结系数,并与文献计算结果进行了对比,结果表明:采用本文方法计算固结沉降速率,可使得最终得到的固结系数准确度大大提高。
The accurate settlement-velocity is obtained by fitting of settlement curve method with MMF curve model, which can be used to evaluate consolidation coefficient. Then the consolidation coefficient which is calculated by the curve fitting method is compared with the consolidation coefficient which is calculated by the difference quotient method in the references. And the result indicates that the accuracy of consolidation coefficient can be improved greatly by using the curve fitting method which is proposed in this article for the settlement-velocity.
