Abstract

A consolidometer for radial drainage under constant rate of strain (CRS) loading was developed. Theoretical solutions for determining the consolidation parameters, such as the coefficient of consolidation, compression index, recompression index, and preconsolidation pressure, from the test results were also proposed. Comparative experiments with CRS loading and incremental loading (IL) were carried out in radial drainage and also in vertical drainage. The results obtained from the developed CRS loading test agreed well with those of the conventional incremental loading test for radial drainage. They also showed that the CRS test enables the whole consolidation test to be completed in 2–6 h for commonly encountered fine grained soils.
