| 摘 要： | 利用地形平面图的数据和有关区域地质资料的数字化方法实现川藏公路典型路段三维地形的显示和实时浏览,为进一步利用地理信息系统进行研究区地层岩性、地质构造和地质灾害分布的叠加分析进行地质灾害研究提供了矢量化的地形底图。川藏公路典型路段的三维地形可视化工作对于川藏铁路的选线、绕避不良地质灾害的发生和开凿铁路隧道的位置选择等将会有一定的参考价值。

| Abstract: | Three-dimensional(3D) display and real-time browsing to the topography of typical segments in Sichuan-Tibet highway are realized by the means of the digitalization to topographical map and regional geological map.The 3D topographical map can provide vectorial base map for the overlay analysis of stratum,lithology,tectonics,and the distribution of geological hazards when utilizing Geographical Information System to further study the geological hazards along the highway.The visualization of 3D topographies for typical segments along Sichuan-Tibet highway would have definite values to the road layout,the bypassing of the geological hazards and the location selection of excavating railway tunnels in Sichuan-Tibet railway design. |
