ANALYSIS OF OVALIZATION OF BURIED STEEL PIPE DUE TO EARTH-FILL

Twin steel pipelines deflected and ovalized 4-5% of the pipe diameter during their installation in 1988 in California. Since the contractor believed field operations were performed according to the specifications, a comprehensive investigation was undertaken, including a geotechnical investigation and a finite element analysis, to determine the causes of the excessive ovalization. The study found that the application of Marston's method on twin pipeline design, based on using a jetted and vibrated bedding material under the site conditions, is greatly impacted by the asymmetrical configuration of the pipes. Deflections are sensitive to the modulus of soil reaction of the bedding material. These and other study findings are discussed.
