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.

Numerical analysis of effects of water leakage with loss of fines on concrete tunnel lining

One of the undesirable effects of water leaking into a tunnel is the loss of fines from the ground behind the tunnel lining. The loss of fines creates erosion voids around the tunnel which alter the stress distribution on the lining.

Calcium leach of a concrete lining under aggressive groundwater conditions

Urban railway tunnels are an important infrastructure for public transportation. A lining of concrete is often cast to support the ground and protect the internal services in the tunnel.
