Non-linear response of the rockfill in a concrete-faced rockfill dam under seismic excitation
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

Seismic reliability analysis of high earth-rockfill dams based on deformation control criteria
The reliability-based design (RBD) is one of the most crucial measures to study and guarantee geotechnical engineering safety. Through quantitative analysis of uncertainty in earth-rockfill dam engineering, the failure probability can be evaluated and ...

A simple permanent deformation model of rockfill materials
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 increases with the confining pressure.

Abstract The Giant Mine (1948–1999) generated 16 Mt of Au‐bearing mill tailings (2800 mg kg−1) originating from a mixture of flotation tailings (84.8 wt%), calcine residues (14.4 wt.%), and arsenic trioxide roaster waste (0.8 wt.%). A water treatment system for high As mine dewatering effluent has operated since the end of mine operations, with the ...

Influence of particle breakage on scale effect of filling characteristics of rockfill material
The filling characteristics of rockfill materials are closely related to their mechanical properties. They can be changed by particle breakage, which is one of the main factors of the scale effect of rockfill materials.
