Dynamic behavior of pile group in liquefied sand deposit


Dynamic centrifuge tests were performed to develop an understanding of soil-pile foundation interaction and to provide data for verification of an earthquake response analysis method for pile foundations in liquefiable soil during earthquakes. Centrifugal test results indicate that pile foundation response in nonlinear liquefied sand is greatly affected by soil behavior due to large ground displacement and excess pore water pressure buildup. The numerical model which consists of beam elements and nonlinear lateral Winkler springs, taking into account the changing effective stress, is discussed by comparing predicted results with measured results.
