Abstract
A series of on-line pseudo-dynamic response tests was conducted to investigate the influence of the degree of consolidation and layer thickness of clay on the earthquake response characteristics of alternating layers of clay and sand. The clay's nonlinear deformation characteristics and their influence on the response of contiguous sand layers were examined. The thickness and configuration of the clay layers were varied to investigate the overall influence of clay layers on the earthquake response characteristics of sand layered with clay. The relationship between the cumulative dissipation energy and the response properties of ground is discussed.
