Morgenstern, N. R., Alencar, J., Chan, D. H.
Abstract: The paper presents the results obtained in the finite element simulation of 8 years of construction of a section of Syncrude's tailings dyke, which is located in northern Alberta and has been used to store oil sand mining waste. The site investigation for the construction of this dyke...

Abstract: In very loose sand, the ratio M-p of shear stress to mean normal stress at the peak point of the undrained effective stress path (UESP) is very close to the stress ratio M at the peak point of the capped yield surface. Stress ratios M-p can therefore be used in constructing yield...

Chan, D. H., Tannant, D. D., Kaiser, P. K.
Abstract: During an excavation-response experiment performed at the Underground Research Laboratory (Atomic Energy of Canada Limited, Pinawa, Man.) a decrease in fracture-zone transmissivity was measured as a tunnel intersected the room 209 fracture zone. The decrease in transmissivity was...

Martin, C. D., Chan, D. H., Kin, J. S., Jeon, J. S.
Abstract: Tunnel construction frequently makes use of radial displacements to monitor tunnel Support performance, particularly in complex ground conditions. In recent years, absolute displacement monitoring methods have replaced the more traditional radial convergence measurements. It has been...

Progressive failure analysis of windrow induced slope movements at the Syncrude Limited mine site
Download1997
Chan, D. H., Mathioudakis, M., Morgenstern, N. R.
The presence of Marine Sediments below the operating bench in the Syncrude Canada Limited oil sand mine (NE Alberta, Canada) has negatively affected dragline mining operation. Any material that exhibits strain softening behaviour is prone to progressive failure. The Marine Clays at the Syncrude...

Abstract: The Canadian geotechnical engineering community has completed a major collaborative 5 year research project entitled the Canadian Liquefaction Experiment (CANLEX). The main objective of the project was to study the phenomenon of soil liquefaction, which can occur in saturated sandy...

Chan, D. H., Morgenstern, N. R., Robertson, P. K., Imam, S. M. R.
Abstract: The relationship between the shapes of the yield surface and the undrained effective stress path (UESP) of loose sand is investigated for triaxial loading conditions. It is shown that the UESP can be used in the construction of capped yield surfaces for sands. The stress ratio M-p...
