Abstract
The Paper describes a method for estimating the one-dimensional consolidation of an aged clay. First, a mathematical model of consolidation is developed by taking account of the properties of aged clays such as preconsolidation and secondary compression effects, and the numerical solutions are presented for some particular cases. By comparison with published experimental results, it is demonstrated that the theory can explain extensively the consolidation characteristics of aged clays. Successively, the determination of the index properties of soil which appear in the theory is considered. The applicability of the theory to practical problems is inferred by comparing with results of model tests in laboratory. Consequently, it is found that the estimate of consolidation by means of the proposed method is fairly surpassing.
