THE EFFECT OF PILE GROUP LOCATION IN SLOPE ON ITS SEISMIC BEHAVIOR

Abstract

IN THIS RESEARCH SHAKING TABLE TESTS WERE CONDUCTED TO INVESTIGATE THE EFFECTS OF THE LOCATION OF PILE GROUP LOCATION ON ITS SEISMIC BEHAVIOR. A CAP SUPPORTED BY A PILE GROUP WAS SET IN A DRY SAND SLOPE, AND SUBJECTED TO SINUSOIDAL BASE MOTION WITH CONSTANT FREQUENCY. SOIL USED IN THIS STUDY WAS FIROUZKOUH SAND 161 WITH 60% RELATIVE DENSITY.THE TESTS WERE SCALED AT 1/10th AND THE PILES WERE MADE FROM ALUMINUM WITH 95cm LENGTH. DISCUSSIONS ARE FOCUSED ON THE BEHAVIOR OF PILE GROUP IN DIFFERENT SITUATION.
