Abstract:The residual deformation behaviors of rock-fill materials were experimentally studied by use of a biaxial apparatus with the medium diameter. The major attention was focused on the influence of the stress level. Based on the test results, the residual deformation model presented by Shen Zhujiang was modified. By use of the modified model, the deformation behaviors of concrete faced rock-fill dams were numerically analyzed. It was shown that the deformation predicted by the modified model was close to that by Shen Zhujiang model for low dams, but with the increase of the dam height and earthquake magnitude, the difference between the two models became larger.
