A departmental report (OUEL Report 2192/98), "Model testing of circular flat footings on uncemented loose carbonate sand: experimental data" (1.3MB pdf), presents the factual results of a series of combined load tests on a circular flat footing on extremely loose uncemented carbonate sand. These tests were conducted to fully explore the concepts of work hardening plasticity theory applied to the behaviour of foundations. Similar tests have been completed on clays and dense silica sand - this set of data is to provide empirical evidence of performance on another diverse material. The analysis of the data has been published in Géotechnique in the article "Observations of footing behaviour on loose carbonate sand" (Paper as pdf (436k)).
