The authors have recently proposed an aseismic reinforcement at the toe of embankment using sandbag-structure which in turn enables one to save the construction cost, to work easily and to reuse the embankment materials. In this paper, the results of static loading test as well as the shaking table test by using a stacking soil-bag are presented. The results of static loading test on the sandbag-laminate showed that the creep of the stacking soil-bag on loading could be greatly eliminated by applying a preloading-prestress cylce. Regarding the shaking table test, the stacking soil-bag structure exhibited almost no deformation as long as the structure is subjected to the prescribed prestress, even when it undertook the lateral load equivalent to the dynamic earth pressure. Based on these experimental results, it was confirmed that the stacking soil-bag structure at the toe of embankment could be a useful countermeasure against the earthquake attacks.
