摘要:BIM技术作为一项工程与信息技术相结合的产物，在促进工程全生命周期信息流动、提高工程建设质量、减少工程建设运营过程综合成本中，起到了至关重要的支撑作用。当前BIM技术主要应用于建筑工程中，对水利水电工程中的应用较少。未解决水利水电工程中的BIM应用问题，本项目在全球最大的沉砂池工程中采用设计-施工周期内BIM持续应用的方法，通过周密的BIM组织和一系列的BIM技术应用，完成了土建异形结构、地形地质BIM模型、钢筋BIM模型、BIM数字档案的一系列应用，从而为本项目的顺利实施打下了基础。本文着重介绍整个项目在组织和应用环境搭建、BIM应用及其效果，为以后的水电站BIM应用给出一个可行性方案。

Abstract: As a product of the combination of engineering and information technology, BIM played a crucial supporting role while promoting the life-cycle information flow of engineering, improving the quality of project construction and management, reducing overall cost of construction and operation process, etc.The current BIM technology is mainly applied building projects, and the application in water conservancy and hydropower projects is less.We use BIM technology in the design of the largest sedimentation basin of the world in CCS project.Thought the careful BIM organization and a series of BIM technology applications, such as special-shaped structure BIM design, BIM application of terrain and geology, BIM application of reinforced bar, BIM-based digital archives, etc., we completed the design and management works in the design and construction stage.This paper focuses on the construction and application of the whole project in the organization and application environment, BIM application and its effect, and presents a feasibility plan for the future application of BIM in hydropower station.
