摘要
根据工程岩体的几何特征,从三维可视化构模的角度上,将工程岩体分为:连续型非褶皱岩体、非连续型非褶皱岩体与褶皱岩体三大类型。提出了适合于非连续型非褶皱岩体三维可视化构模模型,构造了相应的数据结构,开发了表面构模技术用于这类岩体的构模。在此基础上,利用OpenGL技术,在VC++环境下研制了可视化构模系统。利用该系统建立了某岩土工程研究区域的岩体三维可视化模型。
Through analysis of geometrical characteristics, engineering rock-mass is divided into three basic types, continuous non-folded rock-mass, non-continuous non-folded rock-mass and folded rock-mass. An appropriate spatial data model for 3D modeling of non-continuous non-folded rock-mass is proposed, and its corresponding data structure is constructed. A surface modeling technique is developed for building this kind of rock-mass. By using the OpenGL technique, a visual modeling system is developed and used to construct the 3D visual model of rock-mass for a given geotechnical engineering.
