State-dependent 3D multi-mechanism bounding surface model for rockfills
Yantu gongcheng xuebao, 2018 The rockfill materials have been widely used in the construction of rockfill dams due to their high strength, small deformation and strong permeability. The strength and deformation characteristics of the rockfill materials are essential prerequisites to ...

Non-linear response of the rockfill in a concrete-faced rockfill dam under seismic excitation
, 2014 This study investigates the non-linear response of the rockfill in a concrete-faced rockfill dam under seismic excitation for various concrete slab thicknesses from 30 to 100 cm thick. The effect of the friction in the concrete slab rockfill interface on
