Frost heave is an important consideration in the design of buried chilled pipelines. A procedure for calculating the amount of heave under a chilled gas pipeline is presented based on a finite-difference formulation of the heat and mass transfer in saturated soils. The frost heave of the soil is...

A 12m high geogrid reinforced cohesive soil test embankment with 45¯ sides slopes has been built near Devon, Alberta, Canada. The embankment has four test sections: three are reinforced with different geogrids, and one section is unreinforced. The test sections were instrumented with strain...

Abstract: Laterites are the main source of economic metals such as nickel and cobalt. In many parts of the globe, these metals are extracted using the pressure acid leach operation. An efficient rate of sedimentation and a high solids content of the material are two prerequisites for this...

Morgenstern, N. R.

The traditionalconcepts that constitute the framework for geotechnical engineering are often insufficient on their own to provide a basis for solving geotechnical problems associated with frontier resource developments. Studies are reported on the creep of permafrost slopes, the mechanics of...

The unchecked and unnoticed disposal of industrial leachates is a common malpractice in developing countries. Untreated effluents from industries drastically deteriorate the soil, altering nearly all of its characteristics. An increase in urbanization has led to construction on these deteriorated...

Morgenstern, N. R.

At this time, there is a crisis associated with concern over the safety of tailings dams and lack of trust in their design and performance. This crisis has resulted from recent high-profile failures of dams at locations with strong technical experience, conscientious operators, and established...

Sego, D. C., Sasitharan, S., Kilpatrick, B. I., Robertson, P. K., Pillai, V. S.

Abstract: In situ ground freezing to obtain undisturbed samples of a loose sand beneath the Duncan Dam in British Columbia is described. This was the first known use of ground freezing to assist in obtaining samples at depth greater than 10 m in Canada. Once frozen, the sand was cored and brought...

Manahan, P. A., Konrad, J. M., Hofmann, B. A., Sego, D. C., Plewes, H. D., Wride, C. E., Robertson, P. K., Biggar, K. W.

Abstract: One of the primary objectives of the Canadian Liquefaction Experiment (CANLEX) project was to develop and evaluate undisturbed sampling techniques as part of the overall goal to focus and coordinate Canadian geotechnical expertise on the topic of soil liquefaction. Six sites were...

Morgenstern, N. R., Hungr, O.

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...

Kaiser, P. K., McCreath, D. R., Martin, C. D.

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...
