Evolution of structural response to post-trenching of free-spanning submarine pipeline
The free-spanning submarine pipeline has complex interaction with the surrounding soil during post-trenching, but its structural response mechanism is still not verified by physical simulation. Herein, a submarine pipeline model was designed based on the
