Empirical correlations for the compression index of Irish soft soils Available to Purchase

Numerous correlations have been developed in the literature relating the compression index C_c of soft soils to simple index properties that serve as a useful reality check on oedometer test results. However, many of these empirical correlations are specific to soils of a certain geographic region and/or geological origin and therefore may not be applicable in other contexts. Compression index data and corresponding index properties, specific to a good geographic spread of Irish soft soil sites, have been compiled in this paper. Of all the forms of correlation considered, the relationship between compression ratio C_c and the natural water content is the most fruitful in terms of allowing preliminary predictions of compression index to be made.
