Properties and behaviour of Hong Kong marine deposits with different clay contents

Large-scale marine reclamation has taken place on soft Hong Kong marine dep osits (HKMD). More and more reclamation is to be undertaken due to the rapi d development of infrastructures and housing projects. Properties and behav ioural parameters (e.g., consolidation parameters) of HKMD are required for the design of reclamation or foundations on HKMD. The behaviour of HKMD is affected by clay content and other factors. This paper presents results de aling with the (i) composition (content of clay, silt, and sand), (ii) inde x properties, (iii) behaviour during oedometer consolidation, and (iv) stre ngth and deformation behaviour in triaxial compression for HKMD deposits wi th different clay contents. Correlations of the behavioural parameters with clay content and index properties are obtained, presented, and discussed. The correlations and parameter values obtained in the present study follow the same trend as those published in the literature. Limitations on the app lication of these correlations are pointed out.
