Computational modelling of frost heave induced soil–pipeline interaction: II. Modelling of experiments at the Caen test facility

Abstract This paper examines the three-dimensional computational modelling of the interaction between a buried pipeline and a soil region which is induced by effects of differential frost heave. The frost heave generation is modelled by the coupled processes of heat conduction and moisture transport within the soil mass and the mechanical processes in the soil accounts for elastic–viscoplastic phenomena. The pipeline is modelled as a circular structural element which possesses flexural, axial and shear stiffness characteristics. The computational procedures are used to develop estimates for the pipeline behaviour observed in the large-scale experimental facility at Caen, France, which investigated the behaviour of a buried pipeline located at a discontinuous frost heave zone.
