BIM协同设计在海外大型水电工程中的应用及技术研发

Research on BIM Collaborative Design in Overseas Large-Scale Hydropower Engineering and Its Applications

安哥拉凯凯水电站是完全采用欧美标准进行设计和建设管理的跨国别大规模水电工程。工程设计先后基于Dassault CATIA V5和3DExperience的数字化三维协同设计平台,构建了包括地形测量、地质、主电站各建筑物(土建、机电、金结、建筑、监测)、导流洞、围堰等多专业的BIM协同设计体系,并在工程不同阶段完成方案比选与论证、参数化标准化精细设计建模、计算分析、工程制图、工程量统计等应用实践,拟在重点解决基于模型信息的二维工程制图功能优化和研发、复杂异形结构三维配筋等难题,为工程全生命周期的高效化、精细化设计管理提供有效支撑。

Caculo-Caba9 a Hydropower Station is an international large-scale hydropower project in Angola,which is designed,constructed,and managed according to European and American standards.Its engineering design is based on the digital three-dimensional(3 D) collaborative design platform of Dassault CATIA V5 and 3 DExperience,and thus a multi-disciplinary BIM collaborative design mechanism is constructed,which includes topographic surveying,geology,various buildings of the main power station(civil engineering,electromechanics,metallic structure,architecture,monitoring),diversion tunnels,and cofferdam.During different stages of the project,practice and efforts have been made regarding the scheme selection and demonstration,parametric and standard fine design and modeling,numerical analysis,engineering drafting,quantity surveying,etc.The main purpose is to solve the problems such as the optimization and development of two-dimensional(2 D) engineering drafting functions based on modeling information,as well as the 3 D reinforcement for complex-shaped structures.In this way,this research can provide effective support for the efficient and fine design management of the whole life cycle of the project.
