Evaluation of soil-pipe interaction of underwater pipelines in soft soils

Abstract

The paper presents a comprehensive approach to the uniting of models implemented in application-oriented packages. Research findings can be used to design the main pipeline. The modeling and analysis of the stress-strain state of the soil-pipe interaction system are presented herein. This paper analyzes the stress-strain state of the pipeline wall using the ANSYS software package. After the creation of the pipeline solid model, the stress analysis is carried out for all loads calculated at the design stage. The calculation results show that the stress-strain state of the pipeline depends on the depth of its location.
