PORE PRESSURE BUILDUP IN RESONANT COLUMN TESTS

Resonant column tests were performed on fully saturated and dry hollow cylindrical and fully saturated solid cylindrical specimens of Monterey No. 0 sand of 60% relative density subjected to 96 kPa confining pressure. The threshold shear strain amplitude below which no pore water pressure buildup occurs is approximately 1500 for specimens which were not previously shaken. Between the approximate shear strain amplitudes of 1500 and 8500 there was a cyclic strain hardening effect which increased the threshold strain amplitude for specimens which were previously shaken, and caused the pore water pressure of virgin specimens subjected to cyclic strain to stabilize at a predictable level. All specimens liquefied at a threshold strain previously identified to be the shear strain below which gross particle displacement is frictionally blocked.
