Compressibility behaviour of soft cemented soils

Abstract

Analysis of published data on the compressibility behaviour of sensitive soils reveals that it is possible to predict the compressibility behaviour. If the in situ water content and vane strength are known, the e versus log sigma curve can be drawn. Conversely, it is possible to estimate the field bond strengths by superimposing the experimental paths on the contours developed for fixed bond strengths. However, a larger volume of data must be analysed in order to improve the numerical coefficients given in the equations. The authors suggest that the possiblity of extending this approach to stiff cemented clays merits examination.
