MECHANISM OF EARTH PRESSURE AND SIDEWALL FRICTION ACTING ON AN EMBEDDED FOOTING IN DRY SAND BASED ON CENTRIFUGE TESTING

摘要：

Dynamic centrifuge testing of a superstructure-footing-piles model in dry sand deposit was performed, yielding the following conclusions. (1) Earth pressure and wall friction acting on the active and passive sides of the footing were investigated. The hysteresis loop shape of the relative displacement and the wall friction resembles that of the earth thrust. When the total earth thrust amplitude decreases, both sides wall friction tends to act upward on the footing, suggesting that the earth pressure acting on both sides corresponds to the passive side. (2) The sidewall friction and earth pressure acting on the sidewalls of the footing were investigated. The sidewall friction amplitude increases with increasing relative displacement because the earth pressure amplitude creases with increasing relative displacement.
