Uplift Force‐Displacement Response of Buried Pipe

Abstract

The design of buried pipelines in areas of vertical ground movement is governed, in part, by the magnitude of the forces imposed on the pipe and the displacements at which they are developed. An experimental study of these effects, dealing in particular with the influence of soil density and depth of burial, is described. The results compare well with several published models for medium and dense sand, but measured values of uplift resistance are much lower than predicted for loose contractive sand. A simplified procedure that can be applied to the design of buried pipelines is given.
