海洋管线在海洋工程装备中应用广泛，在黑暗未知的海底极易受到船锚、深潜器等水下结构物的意外破环，开展海洋管线平衡位形状态监测研究可有效保障管线的安全。本文基于逆有限元法开发了海洋管线在三维背景洋流作用下的位移场反演模型，包含输入参数模块、坐标转换模块和位移重构函数模块，考虑了悬链线型海洋管线曲率大、三向耦合大位移、局部翻转等特征，解决了三维背景洋流作用下悬链线型管线位移场低模态、不规则给位移场反演带来的技术难题，研究了监测点数量和监测点布置位置对位移场反演精度的影响，测点间距100m、30°布置的方式可满足工程精度要求，研究结果可为海洋管线健康监测系统设计提供一定的思路和方法。

Marine pipelines are widely used in marine engineering equipment, and are highly susceptible to accidental damage from underwater structures such as ship anchors and deep submersibles in the dark and unknown ocean. Conducting the marine pipelines configuration monitoring research can effectively ensure the safety of pipelines. This paper develops a displacement field inversion model for marine pipelines under the action of three-dimensional background ocean currents based on the inverse finite element method. It includes input parameter modules, coordinate conversion modules and displacement reconstruction function modules. The characteristics of large curvature, three-dimensional coupling large displacement, and local flipping are considered. It solves the technical problems caused by the low modes and irregular displacement. The number and layout of monitoring points on the accuracy of displacement field inversion are studied. The arrangement of measuring points with a spacing of 100m and 30°can meet the engineering accuracy requirements. The research results can provide certain ideas and methods for the design of marine pipeline health monitoring systems.
