ABSTRACT
Oblique pipe/soil interaction cases include axiallateral, axial-vertical and lateral-vertical pipe/soil relative displacements which are specific cases of a general 3D (axial-lateral-vertical) pipe/soil relative displacement. This paper presents the experimental study on axial/lateral pipe/soil interaction in dense sand. This study will be followed by a numerical parametric study of oblique pipeline/soil interaction in sand to develop 3D failure surfaces that can be used to define alternative soil springs in conventional design approach.
