In predicting the geotechnical constraint against pipeline movement, it is imperative to properly account for frictional behavior at the pipe-soil interface, especially in the axial direction. The translation angle of the pipeline varies in reality; hence the effects of this variance must be captured in relation to the interaction forces in the lateral, axial and vertical directions. This study focuses on lateral-axial pipeline movement in cohesive soil material. The main finding of the present study is that the incorporation of a shear stress limit in the definition of tangential shear behavior has a considerable effect on the axial pipeline reaction forces. Without the shear stress limit, the axial forces are effectively doubled in comparison to a limit equal to half of the undrained shear strength. There is less of an effect on lateral interaction.
