A numerical investigation on hydro-mechanical behaviour of a high centreline tailings dam.

The high rate of failure in tailings dams reflects the inadequacy of conventional stability and seepage analyses for evaluating their performance, especially during construction. In this article, the hydro-mechanical behaviour of a high centreline tailings dam during staged construction is evaluated by coupled stress-pore pressure analyses.

Numerical analysis of seismic stability of a high centerline tailings dam.

Rapid growth of mining activities parallel with recent technological progresses in this field has led to continuous production of great amounts of mining waste. Tailings dams are constructed to safely store these materials in order to protect the environment and water resources against mineral and chemical contaminations.

Stiffness and strength characteristics of demolition waste, glass and plastics in railway capping layers.

The increased generation of demolition waste has led to the successful implementation of its utilization in civil engineering projects. The combination of recycled aggregates and supplementary materials can potentially improve the quality of geomaterials when constructing alternative railway capping layers.

Cyclic behavior of semi-rigid recovered plastic blends in railway track substructure

Plastic deformation of granular layers in railway tracks under cyclic loading is a key factor controlling the substructure’s stability. In particular, the granular subballast capping layer placed between the ballast and subgrade can undergo permanent deformations due to the moving wheel load of trains

DEM simulation of the thermo-geomechanical effect of recycled concrete aggregate assemblies in geothermal pavement bases

This paper studies the discrete element modeling (DEM) of the thermal-geomechanical effect of recycled concrete aggregate (RCA) assemblies when harnessing renewable geothermal energy from pavement bases. This research study aims to simulate the behavior of RCA under repeated load triaxial test (RLT) at temperatures varying from 20 °C to 80 °C, to simulate temperature effects when harnessing geothermal energy from pavements.

Characterisation of a Deep, Under-consolidated Coal Tailings Deposit

In the Hunter Valley (and in other coal mining regions of Australia) coal tailings typically comprise slurries of low to medium plasticity clay, with the more intractable cases ranging into high plasticity. A combination of high compressibility and low permeability results in deposits having a very low coefficient of consolidation.
