中文摘要：

使用小面积压板在重塑软粘土中进行压板沉陷试验,分析压板尺寸、土壤含水率、土壤密度及样筒筒径对土壤承载力的影响。试验曲线拟合表明重塑土壤的承压特性满足二阶多项式模型。由拟合方程分析可知,模型各项系数随含水率呈对数变化、随土样密度呈线性变化、随着密度和含水率的耦合关系呈对数变化,筒径变化使二次项系数符号发生变化。大田实际土壤的试验表明,其承压曲线也满足二阶多项式模型。

英文摘要：

A plate sinkage test was conducted on remolded soft soil with small-sized plates to determine the effects of plate size,soil moisture content,soil bulk density and the diameter of sampling cores on the soil bearing capacity.Curve fitting on the resultant data revealed a 2nd order polynomial model of remolded soil bearing capacity.Further analysis on the fitted equation revealed a trend of logarithmic variation of each coefficient of the model with moisture content,a linear trend with soil bulk density,a logarithmic trend with the coupling of density and moisture content.The change of core diameter led to a shift of sign of the second order coefficient.A trial test on the field soil also showed a 2nd order trend of the bearing curve.
