SHAKING TABLE TESTS ON LIQUEFIABLE SANDY SOIL REINFORCED BY DIFFERENT LENGTH PILE

摘要

Small shaking table tests were carried out to study the liquefiability of the sandy soil by monitoring the pore pressure during and after the shaking in the model foundation strengthened by different length pile.The result shows that: strengthening the liquefiable sandy soil by sand pile, neither the longer piles produce better effect when same pile spacing; nor the closer piles produce better effect when same pile length. Under certain conditions, good anti-liquefaction result can not be reached by long pile densely placed.
