Modeling pipeline-soil interaction in dense sand using nonlocal Mohr-Coulomb model in a Coupled Eulerian-Lagrangian finite-element code
Pipelines are extremely important for the transportation of oil and gas. Buried pipelines can move in a relatively large distance under special scenarios, e.g. slope failure. Meanwhile, the surrounding soils are subjected to a large deformation. This project aims to develop a computer modeling technique to analyze the large-deformation behavior of soil and its impact on the pipeline. The result will be compared with a previous physical test so that the reliability of this new technique can be evaluated. By using this technique, the reaction load on the pipeline can be calculated, thus providing an input for the design of pipeline.
