The Paper gives an interpretation in terms of the influence of a loading duration on the results of such one-dimensional consolidation test as conducted under the condition of a larger increment ratio, say 1.0. Based on the records of consolidation tests including measurements of both pore-water and total pressures, the role of the adsorbed moisture film with which clay particles are coated or the bonding of those is inferred and the concept of a film bond is introduced. A theory of consolidation is developed with incorporating it. The numerical solutions are presented. It is theoretically shown that such an increment duration as to produce considerable amounts of secondary compression causes the retardation of consolidation. This theoretical result is compatible with that noted and described by numerous observers. Consideration is made of the engineering significance of the parameter β which is introduced for the purpose of a convenient use of the present theory. In addition, the quantitative applicability of the present theory is verified by comparison with the theoretical and the empirical consolidation curves.
