In deep underground excavations in hard rocks where stresses easily exceed the micro-crack initiation stress level inside the rock mass, proper consideration of the behaviour of rockmass during the brittle fracturing process in constitutive modelling is of paramount importance. Current empirical...

An opportunity to re–examine the liquefaction potential of hydraulically placed tailings sand has been provided by the Canadian Liquefaction Experiment (CANLEX). As part of this experiment, undisturbed samples of tailings sand were recovered after freezing the tailings in situ. Examination of...

Abstract: The Highvale mine, west of Edmonton, Alta., is a strip-mining operation with Upper Cretaceous soft sandstone and mudstone overlying the coal deposit. Highwalls cut in the soft rock experienced numerous failures from 1983 to 1985 that disrupted stripping and mining operations and posed a...

The uplift behavior of a shallow pipeline embedded in an elastoplastic medium is examined. An analytical solution for a beam on elastoplastic foundation is developed and a characteristic nondimensional load‐displacement and stress‐displacement relationship are presented. An approximate...

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...

A probabilistic slope analysis methodology based on Monte Carlo simulation using Microsoft Excel and @Risk software is applied to investigate the failure of the Shek Kip Mei cut in Hong Kong. The study demonstrates the techniques used in quantifying uncertainties in shear strength of granitic...

Progressive failure analysis of windrow induced slope movements at the Syncrude Limited mine site

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...

Hendry, Michael T., Roghani, Alireza
This paper presents the quantification of the impact of subgrade stiffness on the prevalence of track geometry defects and degradation of track quality indices (TQIs). The data included in this study come from two high-traffic subdivisions [>50>50 million gross tonnes (MGT)/year] in Canada with a...
