Theoretical Analysis and Experimental Research on Soil Deformation Due to Pipe-soil Interaction for Pipe-laying

摘要

The interaction between pipeline and soil is a difficult problem. This paper focused on the deformation of the seabed due to pipe-soil interaction during pipe-laying, and forecasted the phenomenon of surface upheaval and plastic flow of the surrounding soil with ABAQUS. A formula for predicting the height of upheaval was introduced. An experimental device was set up to analyze the failure mechanism of the soil, and good results were obtained.
