| Abstract | North American Arctic regions contain vast amounts of gas that must be transported through permafrost to reach southern markets. During the 1970s and 1980s, eight full-scale test sites provided information and experience on operating chilled gas pipelines. One site in Calgary investigated frost heave of such buried pipelines. More test sites are unlikely to be constructed because of cost and time constraints. Yet a great deal remains to be learned about frost heave for different soil and groundwater conditions, ditch configurations and potential mitigating measures. Centrifuge modelling of the Calgary short rigid pipelines replicated their behaviour. The heave rate and the amount of heave of a 1.2 m pipeline at two different burial depths at the test site were similar to that recorded in centrifuge tests during 5 hours at 30 g. This paper compares these results to known full-scale behaviour and small-scale laboratory tests for the Calgary site. Small sample frost heave tests and a testbed at Caen are also compared.
