Zhang, G., Brachman, R. W. I., Robertson, P. K.
Abstract: An integrated approach to estimate liquefaction-induced ground settlements using CPT data for sites with level ground is presented. The approach combines an existing CPT-based method to estimate liquefaction resistance with laboratory test results on clean sand to evaluate the...

Robertson, P. K., Wride, C. E., McRoberts, E. C.
Abstract: When sandy soils respond in a strain-softening manner to undrained loading, an estimation of the resulting undrained shear strength (S-u) is required to determine the potential for flow liquefaction at a given site. One of the most commonly used methods for estimating the undrained...

Scott, J. D., Sego, D. C., Zarnani, S.
Abstract: Temperatures were measured along instrumented geogrids to determine thermal strains and their changes with seasonal temperatures. It was observed that the application of temperature correction to the measured strain values by electrical wire resistance (EWR) strain gauges to compensate...

Robertson, P. K., Cunning, J. C., Sego, D. C., Sasitharian, S.
Abstract: The initial state of a sand, defined by the void ratio and effective mean normal stress, can be used to predict its large-strain response. Laboratory studies have shown that the shear-wave velocity of a sand is controlled primarily by the effective confining stresses and void ratio....

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...

Finn, W. D. L., Robertson, P. K., Woeller, D.
Abstract: Impressive progress has been made in the last 25 years in recognizing liquefaction hazards, understanding liquefaction phenomena, and analyzing and evaluating the potential for liquefaction at a site. Recent findings related to the application of the seismic cone penetration test (SCPT)...

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...

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...

Chalaturnyk, R., Azam, S., Scott, J. D.
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...

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...
