Visual simulation system of RCC dam construction process based on OGRE

构建了基于碾压混凝土坝施工过程仿真数据动态交换机制的数据库管理模式,运用面向对象的建模方式建立了系统中不同属性对象的实体模型,并采用面向对象的图形渲染引擎OGRE开发了碾压混凝土坝施工过程三维可视化系统。系统能对仿真方案的调整实时响应并根据仿真结果动态展示坝体施工全过程;通过友好的人机交互功能使用户能够自由观察和查询施工详细信息。系统在某碾压混凝土坝工程中的应用表明,该系统能够提高可视化实现的效率及效果,可为工程施工方案的管理和决策提供信息化支撑。

By creating a database management model based on dynamic simulation data exchange during RCC dam construction process, and constructing entity models with different properties by employing object-oriented modeling method, a three dimensional visualization system for RCC dam construction process was developed by incorporating the object-oriented graphic render engine （ORGE）. This system can adjust the real time response with new simulation schemes and can dynamically display the entire dam construction process. In addition, it provides friendly human-machine functions for users to observe dynamic process and inquire construction information in detail. Application of this system in a practical project demonstrates that, this system can improve the efficiency and quality of visual realization, and can provide information support for construction management and decision-making.
