利用虚拟现实和3dsmax技术进行了截流施工场景三维仿真建模，并在此基础上，结合龙口水力指标的动态计算，提出了基于虚拟现实的截流施工三维动态可视化仿真技术，实现了截流过程的逼真预演和多方案的比较分析，从而为截流组织设计与决策提供了强有力的可视化分析手段。

In this paper, 3D simulation model for the river closure is established by making use of virtual reality and 3dsmax technique. With the analysis of the dynamic hydraulic characteristics at the closure-gap, a VR-based 3D dynamic visual-simulation of method for the complex process of river closure is presented. In this visual epresentation, comparison among different schemes of river closure is achieved easily. Therefore, a powerful visual tool for aiding river closure design and management can be provided.
