Abstract: The method of calculating pipeline stability to floating when constructing submerged crossings in silted and flooded areas is considered. Possible technological solutions are analyzed to fix the pipeline at project levels (fixing the pipeline with anchors in thawed ground , ballasting the pipeline with individual weights and ballasting the pipeline with continuous weight coating).
