Analysis of Ovalization of Buried Steel Pipe Due to Earth‐Fill
Publication: Journal of Performance of Constructed Facilities
Volume 4, Issue 2
Abstract
The causes of out of roundness of a steel pipeline (42 in. nominal diameter and a 9/32 in. wall thickness) due to overburden earth pressure are investigated. It is noted that Marston's method of design for evaluating loads on the twin pipeline, based on the use a jetted bedding material, may be inappropriate because of the asymmetrical configuration of the pipes. The measured data on pipe ovalization are compared with the results of finite element analysis. Key factors relating to the problem are identified on the basis of the comparison of field data and analysis of results. Deflections are found to be sensitive to the value of the modulus of soil reaction of the bedding material.
