TY - JOUR PY - 1993// TI - Characterizing fault rupture hazards for design of buried pipelines JO - Transportation research record A1 - Keaton, Jeffrey R. SP - 28 EP - 34 VL - 1411 IS - N2 - Location of buried pipelines may not be able to avoid fault traces that have the potential to rupture the ground surface. For detailed hazard analysis, geologic evaluation must be done to determine the age and recurrence intervals of surface faulting events. These data, along with the proximity to population as an index of public risk, are used to identify those faults that require pipeline treatment for design. Detailed geologic evaluation also allows characterization of fault movement for pipeline stress analyses. The type of fault, orientation of the fault with respect to the pipeline, direction of movement, and amount of movement must be quantified for stress analyses. The design procedure is iterative and can be done with an analytical or a finite-element method. Variable parameters in the design are unanchored length, pipeline-fault intersection angle, ditch geometry, backfill material properties, pipe material, and pipe coating.
