GIS-Based Three-Dimensional Dynamic Visualization of Construction Diversion for Hydroelectric Project

为直观逼真地描述水电工程施工导流各环节之间复杂的动态时空逻辑关系 ,提出基于 GIS的施工导流三维动态可视化方法 ,构造了施工导流三维动态数字模型 ,并在此基础上实现了模型的动态显示、交互操作、空间分析以及施工导流全过程可视化仿真等功能 ,从而为水电工程施工组织设计与宏观决策提供了一个科学有效的可视化分析手段 .最后给出一个工程应用实例 ,表明文中方法具有较好的实用性 .

A GIS-based approach is presented to visualize the complex space-time relationship among all aspects of the construction diversion of hydroelectric project. The dynamic 3D digital model of construction diversion is built. Then depending on this model, the functions of dynamic display, spatial analysis and interactive operations are developed, and dynamic simulation for the full process of construction diversion is realized. It gives the designers and decision-makers a scientific and effective tool to analyze the design and support decision-making. An example of engineering application is given to show the effectiveness and practicability of this approach.
