三维可视化技术在舟曲县城区灾后重建泥石流防治工程中的应用

结合舟曲县城区灾后重建泥石流防治工程相关数据, 采用3ds Max、 Maya等三维建模软件构建了泥石流防治工程三维模型, 基于Skyline三维GIS平台建立了灾后泥石流防治工程三维可视化场景.对三维可视化场景构建的关键技术、 三维空间数据处理、 三维模型制作和三维场景构建进行详细阐述, 最终建立的舟曲县城区灾后重建泥石流防治工程三维场景将直观、 逼真地显示舟曲县地形、 泥石流防治工程部署情况, 可为今后当地政府防灾减灾工作提供决策支持.此外, 应用目前先进的流体、 刚体动力学模拟软件对舟曲"8.8"特大山洪泥石流灾害过程进行三维动态模拟, 效果比较理想.

Application of 3D Visualization Technology to Debris Flow Control Engineering of Post-Disaster Reconstruction in Zhouqu County

Combined with the data of debris flow control engineering of the post-disaster reconstruction in Zhouqu County, Gansu Province three-dimensional model is built with the software of 3ds model such as 3ds Max, Maya, etc. A 3D visualization scene is also established based on Skyline 3D GIS platform. In this paper, the key technologies of construction of 3D visualization scene, data processing and the process of modeling 3D scene are described in detail. Created 3D scene of post-disaster reconstruction in Zhouqu will visually show its terrain and the circumstances of debris flow control engineering. It will provide a decision support for the local government to manage the similar situation. In addition, the software of the current advanced fluid and rigid body simulation can be applied to dynamic modeling the process of large torrential debris flows, similar to "8.8" debris flow, and the effect will be perfect.
