Axial soil friction is an important parameter for assessing pipeline response to relative ground displacements. Most existing techniques for assessing soil friction are based on experience with piles and can be unreliable for clayey soils, especially near the surface where desiccation of the soil occurs. Unfortunately, pipelines are typically located within this desiccation zone. This paper presents the results from field tests of soil friction forces on pipelines that have been buried for at least 60 years. The results from the field tests are compared with the findings of other recent pipeline research on axial soil friction. Based on the field tests, the adhesion factors developed by Tomlinson (1957) are recommended for use in assessing pipeline response to axial soil movement. Clarification of the reasons for the discrepancy in various test programs is identified as an area for future research.
