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 constructing independent blocks by overlapping， the paper discusses the problem of blocks searching. And the overlapping principle and method of the surfaces with the same and opposite directions are studied. At the same time， the cutting and searching process of blocks is given， which includes the meshing of three-dimensional structural surface， the analysis of intersection about structural plane and boundary， and the searching of key blocks. Based on the principle of overlapping technology， a new searching technique is proposed for identifying the key blocks. With the searching technique introduced into the 3D digital analysis system—the three-dimensional geotechnical structural modeling and analysis system (GeoSMA-3D) developed by ourselves， the searching technique is available to identify the key blocks. Meanwhile， an engineering application is performed to validate the effectiveness of overlapping technology and the superiority of GeoSMA-3D software.

Key words: overlapping technology, block searching, GeoSMA-3D, key block, program development
