大直径深海管道浮体助浮铺设管道变形数值计算分析

以徐圩新区达标尾水排海工程为例，深水海域段排放管铺管施工需要严格控制管道弯曲曲率在允许范围之内，保证管道安全，施工难度非常大。通过介绍能够适应水深较大工况的深海铺管施工方法，对施工工艺参数进行了定量的计算分析，希望能为类似工程提供借鉴。

Numerical Calculation and Analysis of Deformation of Large-diameter Deep-sea Pipeline Laid by Floating Assistance

Taking the Xuwei New District Up-to-standard Tail Water Sea-discharging Project as an example, the laying construction of the discharge pipe in the deep-sea section is required to strictly control the bending curvature of the pipeline within the allowable range in order to ensure the safety of the pipeline, and the construction is very difficult. By introducing a deep-sea pipeline laying construction method suitable for the deep water conditions, the construction technological parameters are quantitatively calculated and analyzed, which can provide the reference for the similar projects.
