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。
The OFFPIPE software is used to carry out finite element analysis on the protection scheme of the submarine pipe trench excavation immersed pipe. The analysis results show that the submarine pipe submerged at the crossing can sink to a predetermined depth and meet the strength requirements.
