Interpretation of piezoball dissipation testing in clay

摘要

Full-flow penetrometers such as the cylindrical T-bar and spherical ball are now being used widely in soft seabed sediments due to their advantages of larger projected area and minimal correction for overburden pressure. A ball penetrometer fitted with one or more pore pressure transducers (piezoball) is of special interest as it can provide information on the soil consolidation properties by means of dissipation tests. Although analytical and numerical solutions have been developed to evaluate
