摘　　要：茂名港吉达港区东二港池1号、2号液体散货泊位工程为独立墩式圆沉箱重力式码头,文中重点研究圆沉箱上部预制盖板和靠船构件分体安装精度控制,在外海无有效掩护海况下,利用BIM技术模拟构件碰撞检测、分体构件钢筋精准对位与临时安装稳性分析,从而优化分体构件结构形式,选取最优吊装方案,细化定位与加固施工工艺,以可视化、信息化、标准化提升预制盖板和靠船构件分体安装精准度和效率,减少项目成本和海上吊装安全风险,为今后类似LPG码头大型预制构件安装提供了经验借鉴。The No.1 and No.2 liquid bulk cargo berths in Jida Port Area of Maoming Port are independent pier type cylinder caisson gravity docks.This paper focuses on the precision control of the prefabricated cover plate on the upper part of the circular caisson and the splitting installation of the berthing components.In the absence of effective cover in the open sea,BIM technology was used to simulate component collision detection,precise alignment of the steel bars of the separate components,and temporary installation stability analysis,in order to optimize the structural type of the separate components and select the optimal lifting plan,refine the positioning and reinforcement construction process,improve the accuracy and efficiency of prefabricated cover plates and berthing components installation through visualization,informatization,and standardization,reduce project costs and maritime lifting safety risks,and provide experience and reference for the installation of large prefabricated components similar to LPG terminals in the future.
