Prediction of Pore-Water Pressure Buildup During Undrained Resonant Column Testing of Virgin Sand Specimens
Prediction of pore-water pressure buildup of a saturated sand deposit subjected to dynamic load is important for dynamic stability analysis of the deposit. Empirical equations, proposed by Drnevich to correlate the predicted pore-water pressure buildup with that measured during undrained resonant column tests on saturated Ottawa silica sand, were used to predict the results of tests on virgin Monterey No. 0 sand specimens. It was found that, with a modification of the coefficient in the empirical equation, there is good correlation between predicted and measured excess pore-water pressures when a high degree of saturation (B ≥ 0.96) was achieved in the specimen preparation. The correlation is poor for specimens with a lower degree of saturation (B < 0.96).
