AbstractThis paper presents a review of some of the anticipated problems associated with the frost heave of an Arctic chilled gas pipeline. The discussions of pipeline design in various locations include unfrozen ground, berm, shallow permafrost, frozen-unfrozen interfaces and river crossings. The author attempts to define the problems as well as prove their existence, their importance, and the necessity to deal with them. The discussions are supported by numerical results from a two-dimensional finite difference heat conduction-convection mode, including gradual phase change. A possible engineering solution to the frost heave problem of a chilled gas pipeline is supported by the experimental results.
