The responses of buried pipelines subjected to a large fault movement are examined based upon a new non-linear cantilever beam analogy. This analogy assumes that the pipeline in the large deformation zone behaves like a cantilever beam subjected to a transversely concentrated shear at the inflection point and a uniformly distributed soil pressure along the entire span. Tangent modulus approach is adopted to analyze the coupled axial force-bending moment interaction effect on pipeline deformation in the inelastic range. Parametric studies of both tensile and compressive responses of buried pipeline to various fault movements, crossing angles, buried depths, pipe diameters and thicknesses are investigated and compared with the previous available results. Stability analysis for the pipeline subjected to a compressive fault is also presented.
