An experiment on the sand layer under impulsive loading

Many studies have been made on the earthquake response of structures on the soil. But many problems are still reserved about the effects of impulsive loading on the soil, assuming the seismic actions as a kind of impulsive ones, i. e., dynamic properties of soil to impulsive phenomena are not fully declared. So we carried out an experiment on the sand layer under impulsive loading and measured maximum accelerations in three places of the sand layer and the stabilities of concrete blocks on the surface of sand. Some experimental results and their conceptions are reported in this paper.
