摘要
本文就利用３Ｄ－ＧＩＳ进行边坡变形的三维空间分析和变形过程的模拟作了一些有益的探讨。为了达到这个目的，作者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 paper discusses on three dirnension spatial analysis of 3D-GIS in the slope detection and simulation of deformation. The authoI combines the character of the slope de1amitation geology configuration, builds tri-prism model by three -dimension visualizing and analyzes data structure and spatia1 data operation of the model. Realizes that tri -- prism model is compatible with the GIS software (such as Arcview) and cornbines with finite - cell (such as DIANA) through ana1ysls. The paper analyzes the slope deformation by the method of tri -prisrn model.
