An analysis of the response of buried continuous pipelines to active faults has led to development of a design guideline for both onshore and offshore pipelines at fault crossings. A fault movement can be resolved into an axial component (parallel to the pipe axis), a lateral component (perpendicular to the pipe axis) in the horizontal plane, and a vertical component. When subjected to bending (lateral oder vertical component) and axial tension force (axial component), a pipeline is likely to fail in tensile rupture. The analytical approach by Kennedy is recommended for calculating the maximum tensile strain in the pipe. When subjected to bending and axial compression, a buried pipeline is likely to fail in wrinkling (local buckling) and a finite-element method is recommended for calculating the maximum compressive strain in the pipe. This discussion focuses in detail on both methodologies and presents two design examples as illustration. Several countermeasures are discussed, and consideration priority is given in selection of countmeasures for typical design case.
