基于WebGL的水电工程BIM正向协同设计应用研究

Application Research on WebGL-based Hydropower Engineering BIM Forward Collaborative Design

针对水电工程设计阶段业务流程复杂、标准不统一、多专业协同困难、模型数据融通不畅等问题,提出以3DWeb GL轻量化显示、三维模型数据解析转换、Web IM即时通讯数据共享等关键技术为依托的BIM正向协同设计解决方案,同时结合移动互联技术,建立了多源数据的多端共享体系,实现了设计阶段各专业设计成果的实时更新共享。基于此,搭建了基于Web GL3D可视化技术的水电工程BIM正向设计协同平台。实例应用效果表明,该系统运行状况良好,实现了水电工程设计阶段各个专业同时在一个云平台内进行正向设计,融合了设计协同、三维模型拼接、二三维联动、碰撞检测、设计成果VR漫游等功能,达到设计、建模、协同、出图、分析一体化的BIM现代化高效设计效果。

To solve the problems of complex business processes,inconsistent standards,multi-specialty collaboration difficulties,and poor integration of model data in the design stage of hydropower projects,a BIM forward collaborative design solution was proposed based on 3D WebGL lightweight display,3D model data analysis and conversion,WebIM instant messaging data sharing and other key technologies.Combined with the mobile Internet technology,the multi-terminal sharing system of multi-source data was established to realize the real-time update and sharing of design achievements of various specialties in the design stage.A BIM forward design collaboration platform for a hydropower project was built based on WebGL 3D visualization technology.The case application demonstrates the operation state of the system is good.In the hydropower project design phase,it realizes the various professional top-down design in a cloud platform,and integratescollaborativedesign,three-dimensional model joining together,two-three-dimensional linkage,collision detection,design results VR roaming and other functions,which achieves the effectiveness of design,modeling,collaborative,integrated analysis of BIM modernization.
