Abstract

In earthquake zones pipeline crossings of major active faults are often unavoidable, and movements of these faults can have serious consequences for the pipeline. The ability of a large diameter shallow-buried pipeline to withstand these movements is studied parametrically. Principal results of the study are summarized herein. Parameters considered include variations in: (1)Fault crossing angle; (2)unanchored length of pipe; (3)depth of burial; (4)wall thickness; (5)pipe diameter; and (6)pipe strength. A simplified procedure accounting for inelastic strains is developed for conservatively evaluating pipeline behavior during fault movement. Results indicate that under suitable conditions, a large diameter shallow-buried pipe can withstand large fault displacements. The procedure can be used to examine many cases other than those considered.
