大阪洪積粘土の圧密特性について

Abstract

In this report the experimental results on preconsolidation pressure values and consolidationcurves of Osaka diluvial clays are presented. They are affected by such factors as pressure incre-ment ratio, loading period etc.The results obtained are as follows;(1) Preconsolidation pressure Pc increases with decreasing pressure increment ratio ⊿p/pirrespective of the samples (Fig-2, 3).(2) Elapsed time until 100 persent primary consolidation becomes longer with decreasing pres-sure increment ratio (Fig-n, 7).(3) For undisturbed samples preconsolidation pressure decreases with increasing loading pe-riod (Fig. 4), but it is inverse for remoulded samples (Fig. 5).
