摘要:

回顾了块体几何识别研究的发展过程,依据模型的空间维数和切割方法将其分为3个阶段,并分类分析了各个阶段的代表性研究成果.从原理、构建、效率和应用等角度对三维块体全空间识别算法进行比较,归纳出块体识别方法的一般数学描述. 指出了当前三维块体全空间识别存在的问题和进一步研究的方向.

关键词: 块体识别, 块体切割, 关键块体理论, 拓扑, 边界表示法

Abstract:

Development of the geometrical identification method of blocks in fractured rock masses is divided into three stages and the representative research results in each of the stages are analyzed. We compare and analyze the typical three-dimensional whole space block identification methods and give a general mathematical description for these methods. The existing problems and topics which need further research are pointed out.

Key words: block identification, block cutting, key block theory, topology, boundary representation
