摘　　要：节理岩质边坡三维可视化模型可以直观地表达边坡结构面的空间展布特征,揭示边坡的破坏模式,是岩土工程研究的前沿和热点课题。为了满足工程建设的需要,在前人对可视化研究的基础上,系统地提出了一套适合于复杂节理边坡三维可视化模型构建的方法。并用VisualC++语言编制成模型构建专用程序,利用OpenGL进行图形显示,做到了任意剖面的截取,并以锦屏水电站边坡为例进行验证,模拟效果良好。The 3D visualization model of jointed rocky side slope can display the characteristics of the spatial combination of structural plane of side slope and reveals the destruction mode of side slope so that it is a forward subject of general interest in the research field of geotechnical engineering. In order to meet the needs of the project construction, based on the research of the visualization by formers, this paper propounds the method for building 3D visualization model of jointed rocky side slope and writes the special program with Visual C ＋＋ computer language, illustrates it by OpenGL. The program can display and capture the random section plane. Then this paper takes the side slope of Jinping Hydropower Station as example for demonstration and gains good simulation results.
