    Abstract

    The potential of piezoball penetrometers to characterise soft sediments was investigated. Novel field and laboratory scale devices were developed and a database of tests In soft soils was compiled. The performance of these devices during normal penetration and dissipation was assessed. The accuracy of strength and consolidation property measurements using the piezoball was evaluated by comparison with other field and laboratory techniques. A new method of Interpreting consolidation characteristics from piezoball dissipation tests was proposed. The effect of the drainage condition on interpreted soli parameters was demonstrated and a means of identifying drainage conditions during penetration was suggested.
