摘要

利用OFFPIPE软件对已建海底管道挖沟沉管保护方案进行有限元分析，分析结果证明，已建海底管道在交越处能下沉至预定深度且满足强度要求。

Abstract

By using OFFPIPE software,the finite element analysis is carried out for the protection scheme of as-built submarine pipeline when trenching and sinking pipeline.The analysis result demonstrates that the as-built submarine pipeline in a place of pipeline crossing can be sunk to a predetermined depth and can meet the strength requirements.
