中文摘要	A series of large-scale cyclic triaxial tests were performed to improve earthen dam seismic designs by studying the deformation mechanism and characteristics of coarse-grained materials during earthquakes. The tests studied the deformation characteristics of coarse-grained materials during cyclic loading of the deviatoric and spherical stresses. The results indicate that the deformation of the coarse-grained materials results from reciprocating deformation and residual deformation related to the cyclic loading time, confining pressure, and dynamic stress ratio. The reciprocating volumetric strain is always negative and twice reached the maximum dilatation during the cyclical changes of the deviatoric stress over each loading cycle.
