Earthquakes cause permanent ground movements that develop soil forces against buried pipelines, thereby causing substantial axial and bending strains. In this study, the force-displacement behavior of buried pipe, subjected to movements consistent with earthquake-induced ground failure, is reported for diameters and depths typical of gas and water utility practice. Using a field-scale test facility, 102-mm-diameter and 324-mm-diameter pipes were displaced horizontally in medium and dense sand at depths ranging from two to 11.5 diameters. The measured forces show consistent trends as a function of sand density and depth-to-diameter ratio, and pipe torque measurements are shown to be small with respect to the strength of the pipe. Displacement fields are described for shallow and deep-seated pipe movements. Recommendations are made regarding appropriate theoretical models for predicting maximum horizontal force and for representing the force-displacement relationships.
