【摘要】：基于单元块体间相互覆盖构建独立块体的原理,探讨块体搜索问题.研究了同向面、异向面的覆盖原理和方法,给出了包括三维结构面网格划分、结构面与边界面的交线分析、关键块体搜索等切割搜索过程.提出一种基于覆盖技术的块体搜索新方法,并将该搜索技术接入自主开发的三维数值分析系统GeoSMA-3D,进行块体搜索.同时,通过工程实例进一步验证了覆盖技术的有效性和软件GeoSMA-3D的优越性.
[Abstract]:Based on the principle of building an independent block between block blocks, the block search problem is discussed. The principle and method of covering the same direction surface and the opposite surface are studied. The intersection analysis of the three-dimensional structure surface mesh, the intersection line analysis of the structure surface and the edge interface, the key block search and other cutting search process are given. A block body based on the cover technique is proposed. A new method is searched, and the search technology is connected to the three dimensional numerical analysis system GeoSMA-3D, which is developed independently, and the block search is carried out. At the same time, the effectiveness of the covering technology and the superiority of the software GeoSMA-3D are further verified through an engineering example.
