Large Scale Modelling of Pipeline/Soil Interaction Under Lateral Loading.

摘要

The purpose of this current research project for the MMS (Minerals Management Service) was: (1) To investigate the effect of submerged testbed conditions on the force-displacement response of a pipe buried in dense sand. (2) To conduct a lateral pipe bending test to higher pipe ovalization levels that those previously accomplished. The results of this project are directly applicable to problems of offshore pipeline/soil interaction resulting from offshore mudslides or as the result of offshore seismic activity. Further, the results are applicable to the previous GSC (Geological Survey of Canada) tests as the soil, pipe, and loading conditions were similar.
