Abstract
One-dimensional compression and creep tests on undisturbed soil samples of Jiangsu marine clay were performed.It was shown that the initial compression index,Cc,and the second compression index,Cα,were related with the natural water content,the initial void ratio and the vertical pressure.Although Cc and Cα were not constant,the two parameters were related in statistical data,and Cα /Cc was approximately a constant.The second consolidationary settlement could be predicted based on Cα /Cc.The results of theoretical prediction basically agreed with the measured data.
