Descriptions
It is important for the aseismic design of the foundation and the earth dam to study the change of shear strength of clay subjected to a earthquake motion. In this experiments, the simple shear test apparatus is used and at first, the specimen was subjected to the required cyclic shear strain and after that, the static shear strength of this specimen was obtained. Fig. 7 shows the typical record and Fig. 8 shows the relation between shear strength ratio τ_<dsf>/τ_<sf>, number of cycles and amplitude of cyclic shear strain. From these results, we may conclude that the shear strength τ_<dsf> decreases in proportion to the amplitude of shear strain and number of cycles, and becomes smaller than the static shear strength τ_<sf> at the amplitude of shear strain above 6%&acd
