大型引水工程施工三维可视化仿真系统研究

为了直观、逼真地描述大型引水工程各环节之间复杂的动态时空逻辑关系，提出了大型引水工程三维可视化图形仿真系统。首先，对引水工程三维可视化图形仿真系统进行系统分析，确定系统的开发模式，然后采集数据并进行了仿真计算，再将所得数据以数据库的形式保存并对数据库进行加工处理，将空间数据（矢量数据、形体数据等）和各种属性信息集成在一起，在这些数据库的基础上建立引水工程三维可视化仿真模型及模型库，以方便对模型进行高效的管理，开发了一个能科学、直观、逼真的表现大型引水工程施工的三维可视化图形仿真系统，为工程施工管理决策提供依据。

Study on 3D Visual Graphic Simulation System for the Construction of Large-scale Water Transportation Project

A graphic simulation system is presented to visualize the complex space-time relationship among all aspects of the construction of large-scale water transportation project. Firstly , 3D visible graphic simulation system of large-scale water transportation project construction is analysed and the exploit method is decided; secondly, data is gathered and simulate calculation is taken, then the data is stored in database and the database is cured, spatial data such as terrain data , shape data and so on, is integrated with all kinds of attribute information, The 3D visual graphic simulation model and model storeroom of large-scale water transportation project construction are founded through the information storeroom,so the models are managed effectively. The large-scale water transportation project construction layout can be represented scientifically, intuitively and realistically and that is helpful for decision of construction management.
