摘　　要：随着虚拟现实技术的发展,三维仿真系统作为一种全新角度的管理方法和技术手段在工程进度管理中起到越来越重要的作用。提出了一种对混凝土坝浇筑过程进行建模以及仿真的方法。对大坝整体模型进行三维裁剪来得到不同浇筑时期大坝的模型,不同于以往工程仿真中对不同时期分别进行建模的方法。并基于Shader Model 4.0构建了实时绘制框架,提高仿真效率。基于上述方法设计实现了一个混凝土坝浇筑过程仿真系统。仿真结果验证了提出的方法可以满足工程需要。Along with the development of virtual reality technology, three-dimensional simulation system as a new perspective of management methods and technical means in the progress of the project management plays an increasingly important role. A new model and simulation method for concrete dam construction process was proposed. Unlike previous works which just create different models for different period manually, the dam model of a certain period could be created by clipping the whole three-dimensional dam model through Three-dimensional clip algorithm. To increase the efficiency for simulation, a real-time rendering framework was constructed based on Shader Model 4. O. And a simulation system for concrete dam construction process was designed and implemented based on proposed method. The results validate that the presented method can satisfy the requirement for project management.
