摘要

The guidelines in the report were developed from a comprehensive analyticalmethodology to assess the three-dimensional stress state imposed in pipelines at railroad and highway crossings, as well as the validation of the analytical models by full-scale field experiments. The result is a design procedure so that uncased pipelines can be installed safely and reliably with respect to the stress environment at transportation crossings. The guidelines apply 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 design procedure for uncased railroad crossings. All of the necessary design curves are given, along with example calculations. A similar document has been prepared for the design of uncased highway crossings (Report No. GRI-91/0284, Guidelines for Pipelines Crossing Highways). A complete technical summary of the research used to develop the design procedures is given in Report No. GRI-91/0285, Technical Summary and Database for Guidelines for Pipelines Crossing Railroads and Highways. The benefits of a more accurate and comprehensive stress analysis procedure affect virtually all aspects of pipeline design. Technology transfer plans have been initiated by GRI to aid in the implementation of these design procedures within the gas industry.
