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.

• 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。
