Modeling and Visualization of Dam Construction Process Based on Virtual Reality

Along with the development of virtual reality (VR) technology, simulation system as a new perspective of management methods and technical means in the progress of the project management plays an increasingly important role. This paper presents a Virtools-based visual simulation method and realizes a concrete dam pouring process. It proposes that the mode of the dam for a certain period could be created by cutting a whole 3D dam model, avoiding creating it manually. The dynamic create of 3D model for dam pouring, particle system for dam flood discharge, and scene roam are also discussed. Meanwhile, the complex processes of dam construction are demonstrated dynamically using 3D animation, which provides a powerful tool for quickly and comprehensively understanding the whole construction process. The system is applied to a Chinese national key project that is XiangJia Dam hydropower project. The application demonstrates that the visual method is effective and feasible, and can be applied to various types of Chinese concrete dam.
