ESTIMATION OF SECONDARY COMPRESSION DURING PRIMARY CONSOLIDATION

概要

論文の詳細を見る
One-dimensional consolidation analysis is described for predicting the consolidation time curve of clays exhibiting secondary compression during primary consolidation. The constitutive soil model is based on the equation governing the secondary compression rate of the decrease in void ratio. This model uses four parameters, Cc, Cc*, Cα and cν* that can be easily determined or assumed from the conventional standard oedometer test results. As a check on the validity of the proposed soil model, the consolidation time curves observed in oedometer specimens are compared with those predicted by the analysis. Satisfactory agreement can be obtained between the computed behavior and oedometer observations. In adition, it is shown that the void ratio rate due to secondary compression during primary consolidation varies to about two degits as much as its final value before the application of the next loading increment.
