Seismic behavior of pile group in soil slope

Abstract

Seismic behavior of pile group in slope is interested for many years by researchers .In this research Shaking table tests were conducted by means of a rigid-box with 1.8m in length, 0.8 in width and 1.2 in height in order to investigate the effects of the location of pile group in sand slope 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 firoozkuh sand 161 with 60% relative density. The tests were scaled at 1/10th and the piles were made from aluminum with 95cm in length and they have fixed head condition .Discussions are focused on the behavior of pile groups in different situations. Main interests are recognition the effect of slope movement and location of pile group on bending behavior of piles.
