Ring shear tests on sand materials have been carried out to show whether there is a change in the behaviour of these materials at high shearing rates and normal stresses. This question is relevant to the problem of the mobility of large rock avalanches (stürzstroms), but is also of more general...

Abstract: A review of underground openings, excavated in varying rock mass types and conditions, indicates that the initiation of brittle failure occurs when the damage index, Di, expressed as the ratio of the maximum tangential boundary stress to the laboratory unconfined compressive strength...

Reclamation of slurry materials such as mine tailings requires effective management of consolidation-induced water release in the long-term. This is particularly challenging for flocculated or thickened tailings which require excessive time to fully consolidate to the final landform due to their...

Croasdale, K. R., Morgenstern, N. R., Nuttall, J. B.
Controlled field and laboratory tests were performed to investigate the relationship between ice strength and the maximum ice pressures on vertical piers. The apparatus used in the field tests consisted of a flat indentor (75 cm wide) which was pushed through the ice by hydraulic rams. 27 tests...

The pressuremeter is a unique method for assessing directly the in situ shear stiffness of soils. However, the correct interpretation and application of the measured modulus must account for the relevant stress and strain level acting around the pressuremeter during the test. A method to correct...

Ferreira, R. S., Robertson, P. K.
Abstract: An interpretation method has been developed to incorporate nonlinear soil behavior to interpret undrained pressure-meter test results. The method makes use of both the loading and unloading portions of the pressuremeter test. The proposed interpretation method accepts that some level of...

Biggar, K., Donahue, R., Sego, D. C., Beier, N.
Abstract: The extraction and upgrading process for bitumen from oil sand deposits in Alberta, Canada currently requires large volumes of process water. This water demand is fulfilled by importing water and recycling/reuse of clarified process water. Reuse of the clarified water results in the...

Abstract: Twenty topples are described from Rock Glacier Site, 2 km north of the summit of the Highwood Pass in the Front Ranges of the Rocky Mountains in Alberta. In situ field testing and laboratory tests indicated that the external force driving the toppling process is frost action within a...

Landslides in weakly cemented glaciolacustrine sediments, Morkill River valley, British Columbia
Download2001
Abstract: Slopes in weakly cemented glaciolacustrine sediments in the Morkill River valley in the Canadian Rocky Mountains stand at up to 70 degrees. Based on field and laboratory observations it appears that a contributing factor to instability is the softening of the soils by frost action and...
