摘　　要：提出用各种线符及其组合概化岩体结构和物性两类信息，并建立起相应的拟合函数，实现工程地质结构及边坡工程开挖的三维模拟和再现。根据实测的离散点信息建立起三维可视化模型，显示任意位置的剖面和平切面图及其它方面的三维计算。最后成功地应用到长江三峡永久船闸边坡工程的三维地质结构模拟和信息的再现。Geoinformation of slope engineering mainly contains rockmass structure and its physical property. 3 D visualization of these informations is a key to establish the model of engineering geological structure. In this paper, different symbols and their combination are used to generalize these geoinformations, and 3 D visualization model of the geological structure is established with the relevant fitting function, which can display successfully geological sections and sterogeological blocks at any different locations. Finally, the presented 3 D model is applied to the permanent slope engineering in the Three Gorges project.
