Frost heave and northern pipelines, state of the art and status of research – three contributing studies / compiled by D.E. Lawrence, S.L. Smith and M.M. Burgess. : M183-2/5004E-PDF

"An application to build a large diameter buried chilled natural gas pipeline to transport Mackenzie Delta gas through the Mackenzie valley to southern markets was filed in October 2004. The frost heave issue that was vigorously debated for similar gas pipeline proposals in the late 1970s is once again relevant. In view of this renewed interest, three review studies on frost heave and pipelines were commissioned by the federal government, under the scientific authority of the Geological Survey of Canada (GSC) of Natural Resources Canada, in 2004. The aim of these studies was to document the current state of knowledge about frost heave theory, testing and predictive modelling, and the application of this knowledge to the design, construction and operation of a buried chilled gas pipeline"--Foreword, page ii.
