| Abstract: The earthquake residual deformation is an important index to evaluating the seismic safety performance of earth-rock dams. According to the researches in the field, the influence of the main factors which plays an important role in the residual deformation characteristics of earth-rock materials was analyzed in this paper, such as density, particle gradation, consolidation stress state, dynamic load amplitude and drainage condition. It is pointed out that there is shortage of the researches of soil stress history,particle gradation,geometrical shape,rock strength and drainage condition,and it is necessary to do further research. The problems of residual deformation models have been analyzed and some suggestions. have been put forward. |
