VR-GIS技术在水利工程“视算一体化”系统研制中的应用

Application of VR-GIS on the development of "watch and calculation integration" system of the water conservancy project

VR-GIS技术结合了虚拟现实技术的可视化特点和GIS的空间分析功能,已经被广泛应用于水利工程的勘测、规划、设计、施工等领域.针对传统的水利工程规划设计中"视"与"算"脱节的不足,提出采用整合虚拟现实与地理信息系统技术,实现水利工程规划设计"视算一体化"系统的方法.并针对水电站水库库容和淹没面积的计算、水利工程施工设计土石方填挖量计算,给出具体的实现方法与过程.

VR-GIS, combined with the visual characteristics of virtual reality technology and spatial analysis function of GIS has been widely used in investigation, planning, designing, construction and other fields of the water conservancy project. Aiming at the disadvantage of the disjoint between “watch” and “calculation” in the traditional planning and designing of the water conservancy projects, it sugguests adopting the technologies of the virtual reality and geographic information System, and discusses the method of realizing the “watch and calculation integration ” system of the water conservancy project planning and designing. Taking calculation of the hydroelectric reservoir storage capacity and the submerged area, the volume of excavation and filling of earth in the water conservancy construction design as example, the paper gives the special method and process.
