PIPE/SOIL STIFFNESS RATIO EFFECT ON FLEXIBLE PIPE BUCKLING THRESHOLD

This paper reports a study of the buckling aspect of various "shape defects" such as flattening or squaring of pipe. The paper discusses pipe stiffness definitions, buckling number, Spangler's model instability, changes in curvature with deflection, time factor, the Luscher model, pipe shape effects on buckling, buckling data, and failure data plot. None of the current buckling models can be used with any degree of reliability to predict the buckling resistance of a flexible pipe because the models allow very weak pipes which actually buckle in the field. There is evidence that a minimum pipe stiffness is required to prevent buckling, through apportioning the pipe stiffness to the loading. The principal determining buckling factor for low stiffness may be the installation procedure which often results in shape defects.
