ANALYSIS OF SEISMIC SETTLEMENTS AND PORE PRESSURES IN CENTRIFUGE TESTS

The paper describes the RSM (residual strain method) and its application to analyze centrifuge tests simulating the earthquake response of a tank foundation resting upon liquefaction-susceptible sand. Analyses were carried out for different values of soil permeability in order to back-calculate the in situ permeability of the sand and to estimate the effect of drainage on permanent settlements and excess pore pressures. The study found good overal agreement between theoretically predicted and measured excess pore pressures and permanent settlements, assuming partially drained conditions with soil permeability similar to that measured in laboratory tests. Comparative studies showed that drainage during shaking may play an important role even in high-frequency, earthquake-like cyclic loading.
