by B. Jay Schrock, JSC Int Engineering, United States,



Document Type: Proceeding Paper

Part of: Pipeline Design and Installation

Abstract: Research in the laboratory and field have been ongoing for the past seventy years on flexible pipe/soil interaction. Virtually all of the early work was done on steel pipe. During the past thirty years most of the evaluation work has been done on plastic pipes. More recently additional information has been developed through Finite Element Analysis (FEA) utilizing the computer with various models and assumptions. Literally thousands of experiments have been conducted and observations made in order to isolate and identify various parameters for a better understanding of pipe reactions to loadings. These parameters, their correct use and the pipes reaction and long term performance are necessary for the pipeline designers. The paper presents an overview and summary of the various results of much of this research and testing.
