The results of consolidation analyses on settlement are compared with the actual settlements observed at a reclaimed land where Holocene clay was underlain. This alluvial clay deposit with a relatively high pre-compression stress settled about 1.3 metres at the location of the thickest deposit as reclamation work made progress. It is found that the analytical results based on the constant. strain-ratc oedometer test match the actual settlements better than those based on the standard oedometer test. This indicates that the pre-compression stress of this clay should be determined by a constant strain-rate oedometer, and that the stress-strain relation obtained from this test can directly be used for consolidation analyses on settlements at this site.
