Abstract: The problem of the elastic interaction is examined between a pipeline or a group of connected flexible connected pipelines and the surrounding soil medium, which is induced by ground movement. The pipeline is modelled as a structural element in which flexure takes place only in the longitudinal direction. An approximate method for estimating the flexural moments that are induced in the vicinity of a transition zone is presented. The techniques proposed in the paper can be used to examine the flexural interaction between both near surface and deeply embedded pipelines located in a transition zone.
