三维地层开挖的可视化表达方法与实现

Visualization of Three-dimensional Stratum Excavation Methods and Implementation

智慧城市实际上就是利用现代化信息技术,实现对城市的智慧管理。城市市政工程中地层智能开挖和智能施工是智慧城市运用现代化信息技术的重要标志。GIS三维可视化的主要工具之一就是Arc Scene,是三维可视化的展示平台。本文主要通过ArcEngine组件库,以钢企管线管理平台为例,利用多面片理论,详细地介绍了从三维地层的开挖区域选择,到开挖基坑的实现,再到施工量的计算整个流程,最终为城市或者工厂地下施工的设计者和决策者提供依据。

Actually, the smart city aim to achieve the intelligent management for the city by using modernized information technology. A significant symbol of smart city to use the modernized information technology is the formation of intelligent excavation and intelligent construction in urban municipal engineering. One of the major tools for three - dimensional geographic information system is ArcS- cene, which is the show platform for 3D visualization. This paper mainly through Arc Engine component library, took the steel plant pipeline management platform for example, using multi - surface sheet theory the paper introduced the entire excavation process in de- tail which from the excavation area of the three - dimensional stratum to the achievement of the excavation pit and the calculation of construction volume, eventually provided the basis for the designers and decision - makers that devoted to underground construction of cities and factories.
