In this paper, a study has been made to obtain the macro deformation of clay skeleton as accumulation of micro displacements of clay segments with which the clay skeleton is composed. The joints of clay segments are classified in assumption into two types : the one is the joint where no relative sliding is thought to occur between the segments though variation is produced in the intercepting angle between the segments by external stress. In the other type of the joint, the segment slides on the surface of the adjacent segment holding the adsorbed water around the joint, when the force applied on the segment exceeds the frictional resistance between the segments. The probability of the sliding segment is calculated under the assumption that the applied force and the frictional resistance are distributed as certain Gaussian distribution functions. The resisting forces on the sliding segment are assumed to consist of the following 3 forces : the recovering force due to the imbalance of repulsive force and the attractive force existing between the segments, the viscous resistance of adsorbed water which is considered as Eyring's viscosity and the frictional resistance between the segments. From these considerations, the mechanical model has been obtained as shown in Fig. 3 which represents the rheological behaviour of clay skeleton accompanying neither consolidation nor fracture.
