摘　　要：针对传统裂隙结构面特征分析中未考虑样本过渡信息的不足,将模糊信息分配法应用到裂隙结构面特征分析中。介绍模糊信息的基本原理、一维及二维模糊信息分配公式和模糊信息矩阵,阐述基于模糊信息分配法的裂隙结构面玫瑰花图、极点图、等值线图和模糊频率直方图的绘制方法。使用该方法对实际野外调查的裂隙产状和间距数据进行分析,并对比传统方法统计结果,研究结果表明:该方法所得结果的统计特征更加明显和准确;方法提取样本点的过渡信息,避免统计结果受样本点波动的影响,具有更好的稳定性。In view of the deficiency of traditional fissure structural plane analysis without considering the transitive information of samples,fuzzy information diffusion method was applied to the fissure structural plane analysis.One-dimensional and two-dimensional fuzzy information diffusion formula and fuzzy information matrix were introduced respectively.Furthermore,based on fuzzy information diffusion method,drawing methods of rose diagram,pole diagram,contour diagram,fuzzy frequency histogram of fissure structural plane were established.The case study shows that this method could extract the transitive information of samples well,avoid the effect of the sample variations to statistical results and also increase the stability of the statistical results.
