The overall objective was to provide guidance for proper design of profile-walled pipe. Data from buried pipe tests in the soil cell at Utah State University for thirteen different pipe samples were included in the study. Parallel plate tests were also completed on these pipe samples. The primary objective of the research was to correlate previously completed buried pipe tests of a variety of pipe designs and to determine what conclusions could be drawn. Data from 39 buried pipe tests were analyzed. The buried tests were at 75, 85 and 95 percent of standard Proctor density. This paper summarizes the results of that study and focuses on the tests buried in 85 percent dense soil. The identities of the pipe manufactures are not disclosed and pipes are only described in terms of basic parameters such as cross-sectional area and area moments of inertia. A large portion of this paper focuses on finite element analysis results to confirm and extend the results from the physical tests. Design limits are recommended for several dimensionless parameters that describe profile geometry. One of the significant conclusions of this study was that pipes with profiles that perform well when buried in soil also perform well in a parallel plate tests.
