摘要

The report focuses on four areas including: (1) review of the design and construction recommendations put forth by various professional and regulatory institutions as well as performance records of pipeline crossings beneath realroads, (2) description of the construction techniques used to install pipelines beneath railroads and evaluation of soil dead loads and traffic related live loads acting on the pipeline, (3) review of general methods employed for corrosion protection and the difficulties associated with implementing a protective system, and (4) summary of current design practices, along with their historical development, and newly devised analytical methods used to model the stresses and deformations in buried pipelines.
