Construction-Induced Dynamic Pressure and Corresponding Impact Factors for Pipelines

by Mark C. Gemperline, US Bureau of Reclamation, Div of, Research & Lab Services, Denver, CO, USA,



Document Type: Proceeding Paper

Part of: Advances in Underground Pipeline Engineering

Abstract:

The Bureau of Reclamation, U. S. Department of the Interior, conducted a study which measured pressure exerted by construction scrapers on a rigid, buried, instrumented concrete slab. Impact factors were determined for several conditions which could occur during construction operations. The two factors found to be most significant were roughness of the ground surface and scraper speed. Factors found to have little influence on the computed impact factors were depth of soil covering the concrete slab and soil types used in the test. As expected, the measured impact pressures increased as the depth of cover decreased. Computer impact factors ranged from 1 to 3. The study results also imply that, under certain conditions, impact factors larger than 3 are possible.
