ANALYTICAL STUDY OF STRESSES IN TRANSMISSION AND DISTRIBUTION PIPELINES BENEATH RAILROADS. TOPICAL REPORT OF TASK 2, JUNE 1985-FEBRUARY 1F987

The report presents a critical evaluation of existing analysis and design techniques for buried pipelines crossing railroad rights-of-way and identifies factors that require thorough investigation. The primary result is a more refined and comprehensive methodology for the design of buried pipeline crossing of cased and uncased carrier pipe. Modifications to current design practice are propossed with the major features being: 1) refined definitions of loads, deformations and stresses affecting the buried pipe, 2) the use of a multi-axial yield criterion to define the yield condition of the pipe, and 3) the inclusion of fracture and fatigue control criteria. Flow charts of the proposed methodology and necessary deesign curves are included.
