Third party utility and pipeline crossings are common construction projects in the railroad industry. Trenchless construction methods are typically used for the installation of third party crossings within a railroad right-of-way. The American Railway Engineering and Maintenance-of-Way...

In mining operations, seepage from tailings and mine rock stockpiles typically contribute a small percentage of the overall site wide water balance yet their effect on water quality is often disproportionate due to leaching of oxidized products as acid rock drainage. Most site-wide water balance...

Tays, D., Scanlan, K., Macciotta, R., Martin, C.D., Hendry, M.T.
This report summarizes the Canadian Rail Research Laboratory’s (CaRRL) findings after performing an in-depth investigation into the potential safety benefits gained from the introduction of enhanced train control (ETC) technology to the Canadian railway environment.

Cation exchange due to the diffusion of ammonium from livestock effluent through glacial clay soils
Download2007
Abstract: The objective of this study was to experimentally simulate interactions between liquid manure and soil in diffusion-dominant areas beneath earthen manure storage (EMS). A previous radial diffusion cell method was modified to include an anaerobic chamber that employed a plastic glove bag...

Stability charts are presented to facilitate the computation of the factor of safety of earth slopes during rapid drawdown. As the reservoir level is lowered, the factor of safety decreases if it be assumed that no dissipation of pore pressure occurs during drawdown. Pore pressures during...

Robertson, P. K., Skopek, P., Sego, D. C., Morgenstern, N. R.
Abstract: Loose cohesionless saturated materials have proved responsible for a number of serious or catastrophic flow slides. Liquefaction failures with no obvious triggering mechanism have also been recorded. This phenomenon of sudden liquefaction without a presence of cyclic shear stresses is...

This survey is written to document a standard protocol for identifying mass-volume relationships for tailings materials. The need for establishing a standard protocol has arisen in the oil sands mining industry as different engineering disciplines; geotechnical, mining, chemical and mechanical,...

Guenot, A., Morgenstern, N., Kaiser, P. K.
Tests on small circular openings have been conducted to investigate the deformation processes near tunnels at large depth or in weak rock. The test equipment has been described in Part 1; typical test results documenting the behaviour of small tunnels in a jointed rock mass with time-dependent...

Design and performance evaluation of vertical shafts: rational shaft design method and verification of design method
Download1988
Ground deformations around axisymmetric shafts cannot be determined with the design approaches currently available, which are mostly based on plasticity methods. The convergence–confinement method (usually applied to tunnels), with consideration of gravitational effects and the three-dimensional...
