A comprehensive methodology is being developed for evaluating stresses in natural gas pipelines at railroad and highway crossings. The methodology accounts for soil-structure interaction and the three-dimensional distribution of pipeline stresses. The methodology involves delineating field loads and geometries through detailed site observations and discussions with industry personnel, and using computer graphics to analyze pipeline stresses under the complex three-dimensional conditions which prevail in the field. Field experiments will be performed to substantiate the predicted pipeline stresses at railroad crossings. Guidelines will be developed for pipeline crossings acceptable to representatives of gas, railroad, and highway industries.
