Abstract

Modified Rowe cells were used to examine the behavior of soft clays during radial consolidation induced by vacuum pressure. Degree of consolidation (DOC) in relation to the coefficient of radial consolidation (ch) based on measured strain and excess pore-water pressure was compared. The value of ch based on excess pore-water pressure is shown to be less than that based on strains. The vacuum pressure-total surcharge ratio (VSR) is found to be an important parameter influencing the rate of the consolidation. Moreover, the coefficient of radial consolidation based on conventional oedometer testing could not accurately predict the consolidation behaviour of soft soils under different VSR. Finally, a semi-empirical model incorporating the relationship between VSR and a modified coefficient of radial consolidation is introduced.
