Abstract
This paper deals with the theoretical part of the investigations of the effect of side friction on the process of the one-dimensional consolidation.On the basis of the characteristics of the frictional resistance and the compressibility of soils, three kinds of fundamental equations are derived and numerically solved. From the view point of the routine methods for determining the coefficient of consolidation and volume compressibility, it is indicated clearly that the side friction has completely opposite effects on the time rate and the amount of settlement depending on the relation between the void ratio and consolidation pressure, and that the characteristics of the one-dimensional consolidation affected by side friction can be classified into four categories by the characteristics of compressibility and friction of soils.
