Descriptions
Usually, as earth structures are subjected to earthquake motion, strength of soil decreases by the cyclic loading and structures become unstable. In this study, we define that shear strength of the foundations immediately after earthquake is dynamic shear strength (τ_<dsf>), and investigate the relation between dynamic shear strength, cyclic shear strain amplitude (γ_d) and number of cycles (n). In this experiments, the simple shear test apparatus is mainly used, then the results of several sorts of soil samples are compared and examined. Besides, excess pore water pressure during shear tests is measured and dynamic characteristics of the cohesive soils is investigated in view of this behaviour.
