The overall goals of the research were to develop a comprehensive analytical methodology to assess the three-dimensional stress state imposed in pipelines at railroad and highway crossings, validate the analytical models by full-scale field experiments, and establish a design procedure so that uncased pipelines can be installed safely and reliably with respect to the stress environment at transportation crossings. The research applies to steel pipelines for natural gas transmission and distribution systems, normally installed with auger boring and pipe jacking construction methods. The report represents a summary of the analytical and experimental research used to develop the design procedure. Details of the analytical models are given, along with documentation of the experimental procedures and measurements. The report focuses on: (1) analytical techniques for evaluating earth and live load stresses, (2) the development of a comprehensive design methodology to evaluate stresses on uncased gas pipelines, (3) presentation of the database collected from full-scale field experiments, (4) comparisons between current design practice and the newly developed methodology, and (5) comparisons between the results predicted by site-specific numerical models and those measured during the field experiments. The volume is the Executive Summary.
