| Abstract | The experimental behaviour of model pipelines embedded in polycrystalline ice is studied to improve theunderstanding of the behaviour of a chilled buried pipeline subjected to frost heave. Two model pipelines withslightly different radius to thickness ratios were subjected to prescribed displacement rates. Their behaviourwas monitored until peak strains corresponding to current acceptable strain limits, often referred to as the wrinkling strains, were exceeded. The sizing of the model pipelines and experimental setup are described and detailed procedures on polycrystalline ice sample preparation are given. Representative core samples of polycrystalline ice were tested to determine its elastic and creep properties. The observed and predicted responses of strain histories in the pipeline are compared and acceptable agreement between the responses is obtained. |
