Abstract
A method of conducting model experiments on wave propagation phenomena caused by irregular ground was developed. Acrylamide gel was used as the ground model material, which slows down the wave phenomena because of its low elasticity. The ground model layers were made on a rigid base. The left-side layer of the ground model and two right-side layers were connected at the center of the model. By inducing SH waves in the vertical direction, wave phenomena due to the irregular ground were researched. The following results were obtained in (1) Love waves in the horizontal direction produced in the two-layer ground were verified. (2) In the vicinity of irregular part, wave phenomena depended strongly on body waves. The applicability of this method was thus demonstrated.
