Abstract
A granular air-mortar is a light weight backfill material and it's unit weight and strength can be control. Therefor it is estimated to reduce earth pressure acting on the revetment and the retaining wall. In the case of using this light weight material at a revetment, liquefaction and seismic earth pressure of backfill are difficult planning problems. And so static and cyclic triaxial tests and shaking table tests were performed on a granular air-mortal. This report deals with the shear characteristics and the seismic earth pressure acting on the retaining wall.
