Abstract: This paper discusses the frequency of occurrence of anomalous consolidation behaviour. The behaviour of soft clay is discussed briefly in terms of the effective stress path/yield envelope method of analysis. About 20 case records have been analyzed to determine the field effective stress paths and associated yielding of the foundation clays. The case records analyzed include a variety of soil types, loading and stratigraphic geometries, and boundary drainage conditions. Sites at which vertical drains/wicks were and were not used to accelerate consolidation are also included.
