LATERAL RESISTANCE OF PILE FOUNDATION ESTIMATED BY CENTRIFUGE AND BLIND TESTS ON SOFT GROUND

Abstract

The centrifugal model test with the soil-pile-structure system was performed for the dry Toyoura sand layer. In order to investigate the applicability of the seismic deformation method and the Chang equation as the prediction method, the pile response was estimated before the test. The time history response analysis was also carried out. The analysis result was compared with the test. It was found that it may be better to take into consideration the ground displacement caused to an earthquake for evaluation of pile response on the non-liquefying ground.
