ABSTRACT: A conventional pipe stress analyses often idealizes the pipe soil interaction with a beam-spring finite element model where independence is assumed between reactions in axial, lateral and vertical directions. There is however interdependence between these springs as recognized in recent PRCI guidelines. This paper highlights the development of a 3D soil-spring interaction model based on a continuum finite element analysis approach. For the constructed landslide scenarios considered in application of the model, the directional dependency is shown to change the accumulated plastic strain profile in the pipe.
