基于Web3D技术的工程施工可视化仿真应用研究

Study on application of visual simulation for hydraulic engineering construction based on Web3D technology

为了直观地表述水利水电工程施工过程和施工形象,并对来自工程施工的信息进行管理和分析处理,以提高水电工程施工过程信息化管理与决策水平,结合长江三峡工程二期厂坝施工的实践,应用VRML虚拟现实建模语言及PHP动态网页技术,实现了基于网络三维技术(Web3D)的水电工程施工过程可视化仿真和施工信息的交互式查询,为施工管理决策者提供了远程科学决策的信息支持。

For describing construction course and construction image vividly, and managing the information from the project construction, this paper applies Virt ual Reality Modeling Language (VRML) and DHTML technology to visual simulation o f the second-phase of Three Gorges Project in the Yangtze River, studies and rea lizes the interactive query information of hydraulic engineering construction, o ffered sustaining information to administrator in order to facilitate the scient ific decision-making process, in favor of advancing technology of hydraulic engi neering construction and improving the level of management.
