Method for Determining Rheological Model of Soft Soil Based on L S Solution of Overdetermined Linear Equations

为研究软土流变特性,利用超定线性方程组的最小二乘解,拟合了流变试验的最优逼进多项式。根据最优多项式,可以对照归一化元件模型确定流变模型及其参数,通过流变试验验证了这种方法的合理性,为流变模型辨识及其参数确定提供了一种新方法。

In order to study the rheological property of soft clay, the best - fit polynomical approximation is fit based on L S solution of overdetermined linear equations, according to which rheological model and parameters can be calculated upon matching normalized element model. A new method for identifying rheological model and calculating parameters is provided and verified by rheological test.
