Abstract

This study describes the compressibility of marine clays at southern and western coasts in Korea. In order to evaluate the effect of disturbance on the compressibility, a series of various laboratory consolidation tests are performed on the specimens obtained by large block sampling and piston sampler. It is observed that the volumetric strain of large block sample is smaller than that of piston samples and the compression index of large block sample is larger than that of piston sample. An empirical equation of compression index is suggested in this study, considering the effect of sampling. The usage of suggested empirical relation is expected to provide more reasonable prediction of settlement than using the compressibility obtained from the result of tests on piston samples.
