Abstract:

A number of large-scale reclamations have taken place in the coastal areas of Korea. Very thick soft ground composed of marine clayey deposits is distributed along the coastal areas of Korea. More and more ground improvement has been conducted due to the rapid development of infrastructure and housing projects. As the consolidation behavioral parameters are required for the design of reclamation, the compressibility characteristics of four marine deposits were investigated by means of one-dimensional consolidation tests. This article presents results dealing with the (i) primary and secondary compression during oedometer consolidation, (ii) long-term secondary compression (creep), and (iii) correlations with index properties. The new equations obtained from correlations are presented and discussed.

Keywords: compression index; consolidation; creep; marine soft clay; recompression index; secondary compression index
