摘　　要：针对高拱坝施工过程的复杂性,提出把虚拟现实技术应用到施工仿真建模中,开发了虚拟场景下的高拱坝施工仿真系统。对系统进行了详细介绍,主要包括:系统实现功能以及开发流程,虚拟场景建模方法和系统实现所采用的一些关键技术如纹理映射技术、碰撞检测技术、场景漫游技术、三维模型拾取与反馈技术等。开发出的系统结合工程实例进行了应用,为此工程的施工组织设计和辅助决策提供了科学有效的手段。As complexity of high arch dam construction process, the virtual reality technology was applied into the construction simulation modeling and a construction simulation system under virtual scene was established. The system was introduced in detail including the functions and the developing process, the virtual scene modeling methods and some key technologies such as texture mapping, collision detection, scene walkthrough, picking up and feedback of 3D objects. An engineering example shows that the system provides a scientific effective tool for construction design and decision-making.
