| 中文摘要: |
| 国内港口和航道工程中，水上打桩作业通常采用多点锚泊打桩船和平板驳，打桩前应规划好两船各缆绳的下锚位置，避免缆绳与周围结构的碰撞、缆绳与缆绳之间的刮蹭，并确保各缆绳有足够的长度以保证足够的锚力。西非某离岸式油码头锚泊条件较差，采用带液压支腿的平板驳（下称支腿驳）替代常规平板驳,成为“喂桩船”的一种新形式。基于支腿驳的应用，介绍了支腿驳稳定性的分析方法，采用有限元与静态系泊分析相结合，解决支腿驳结构的验算问题。支腿驳采用支腿进行锚定，操作便捷，尤其适用于水深较浅，表层土较弱的情况，可供相关行业在近海施工船舶选择时参考。 |

| Multi-point anchoring pilling vessel and flatbed barge are usually adopted for piling work on water in domestic port and waterway projects.Before driving piles,the anchoring positions of each cable of the two vessels should be planned to avoid collisions between cables and surrounding structures,as well as scratches between cables.It is also necessary to ensure that each cable has sufficient length to ensure sufficient anchoring force.The anchoring conditions of an offshore oil terminal in West Africa are poor.A flatbed barge with hydraulic support studs (hereinafter referred to as the stud barge) is used instead of a conventional flatbed barge,becoming a new form of “piles carrier”.This article introduces the analysis method for the stability of the stud barge based on its application in this project,using a coupling method of finite element analysis and static mooring analysis to verify of the stud barge structure.The stud barge is anchored with studs,which is convenient to operate,especially suitable for shallow water and weak topsoil.This paper can be used as a reference for relevant industries when selecting offshore construction ships. |
