【摘要】：随着计算机和测绘技术的进步,三维地理信息系统(3DGIS)以其直观、真实、可视化及空间数据与空间关系分析能力,正逐渐在各行各业中得到应用。水电站的建设水电站施工往往是一项长久而复杂的工程,其中存在这许多问题,例如总体预计的施工进度安排与各个建筑物构建的施工进度安排,空间位置上的逻辑关系、施工期内洪水的流域方向、防洪导流对施工的影响难以用简单的表格图片或单纯的数学模型来表示。三维地理信息系统能为水电站规划、设计、施工、管理过程提供一个形象直观、科学简便的可视化分析手段,有助于推动水电站智能化、现代化的发展,为社会创造效益,正逐渐在水电站建设项目中得到应用。本论文是以丽江市梨园水电站三维地理信息系统建设项目为依托,以水电站三维地理信息系统的实现为目的,对三维地理信息系统的理论知识进行了详细阐述,在了解三维GIS理论的基础上对三维建模方面的知识也进行了深一步的探究,对实地数据进行了现场采集,最后对水电站的地表建筑进行了构建。基于水电站地形的复杂特殊性,运用TerraBuilder对梨园水电站的地形进行地面修整,例如三维模型与三维地形契合问题以及水面道路的修正问题等。最后根据业主方要求制定了适当的设计技术路线,并最终以Skyline为基础平台完成了对梨园水电站三维地理信息系统的开发实现。
[Abstract]:With the development of computer and surveying and mapping technology, 3D GIS (3D GIS) has the ability of visualization, visualization, spatial data and spatial relationship analysis. The construction of hydropower stations is often a long and complex project, in which there are many problems. For example, the overall estimated construction schedule and the construction schedule of each building arrangement, the logical relationship in the space location, the river basin direction of the flood during the construction period. The effect of flood control and diversion on construction is difficult to be expressed by simple table pictures or simple mathematical models. Three-dimensional GIS can provide a visual and visual view for the process of hydropower station planning, design, construction and management. The scientific and simple visual analysis method is helpful to promote the intelligent and modern development of hydropower stations and to create benefits for the society. This paper is based on the construction project of Liyuan Hydropower Station in Lijiang City, and aims at the realization of 3D GIS of hydropower station. The theoretical knowledge of 3D GIS is described in detail, and the knowledge of 3D modeling is further explored on the basis of understanding 3D GIS theory, and the field data are collected in the field. Finally, the surface building of the hydropower station is constructed. Based on the complex particularity of the topography of the hydropower station, the terrain of Liyuan Hydropower Station is repaired by TerraBuilder. Such as 3D model and 3D terrain fit problem and surface road correction problem. Finally according to the requirements of the owner to formulate the appropriate design technical route. Finally, the three-dimensional GIS of Liyuan Hydropower Station is developed based on Skyline.
