Abstract

When the industrial complex creation and the structures are constructed on the soft clayey ground, the long-term consolidation settlement greatly becomes a problem. In the present study, long-term consolidation tests to examine the change in the coefficient of secondary consolidation by the influence of the initial consolidation load and the influence of the consolidation load increment ratio($\Delta_p/_{p_0}$) in the normally consolidated state with an improved standard oedometer tester were examined. In addition, the finite difference method was executed by using one dimensional Elasto-Viscous model proposed by Yoshikuni et. al. From the result of the numerical analysis of the comparison laboratory tests, the applicability of the Elasto-Viscous model was verified from the agreement of the secondary consolidation process.
