A simple permanent deformation model of rockfill materials

Water Science and Engineering, 2018
Existing experimental results have shown that using a semi-log linear relationship between the permanent volumetric strain and cyclic number underestimates the volumetric deformation of rockfill materials with a large cyclic number, and that the error ...
