Abstract
One of the primary objectives of the Canadian Liquefaction Experiment (CANL EX) project was to evaluate in situ testing techniques and existing interpr etation methods as part of the overall goal to focus and coordinate Canadia n geotechnical expertise on the topic of soil liquefaction. Six sites were selected by the CANLEX project in an attempt to characterize various deposi ts of loose sandy soil. The sites consisted of a variety of soil deposits, including hydraulically placed sand deposits associated with the oil sands industry, natural sand deposits in the Fraser River Delta, and hydraulicall y placed sand deposits associated with the hard-rock mining industry. At ea ch site, a target zone was selected and various in situ tests were performe d. These included standard penetration tests, cone penetration tests, seism ic downhole cone penetration tests (giving shear wave velocity measurements ), geophysical (gamma-gamma) logging, and pressuremeter testing. This paper describes the techniques used in the in situ testing program at each site and presents a summary and interpretation of the results.
