摘　　要：利用 3D -GIS进行边坡变形的三维空间分析和变形过程的模拟探讨。为了达到这个目的 ,结合边坡地质结构呈层状的特点 ,采用三棱柱模型对边坡进行三维可视化数据建模 ,并分析了该模型的数据结构和空间数据操作。通过分析可知三棱柱模型能与现有的GIS软件 (如Arcview)兼容 ,也能与现有的有限元软件 (如DIANA)相结合 ,利用柱体分析法对边坡进行变形分析。The three dimensional spatial analysis and the deformation process simulation of monitoring landslide applied with three dimensional GIS are discussed in this paper. Triangle Prism Network (TPN), a kind of spatial data model, is selected based on geological characteristic of layer shape. This model has its spatial advantages in geology GIS, and it can be carried out easily by extending current 2D-GIS software such as Arcview. The data structure and spatial data operation of TPN spatial data model are analyzed in the paper. It suggests that TPN spatial data model is suitable to landslide deformation analysis applied with Finite Element and prism analysis way.
