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.
