摘要 岩体裂隙的方向性研究为裂隙几何描述的突破口,而裂隙玫瑰花图是裂隙方向统计数据的主要表达方式之一,过去大多采用人工统计手工绘制的方式实现,效率低。因此,按裂隙宽度将裂隙分为大、中、小、微小裂隙,借助ArcGIS和Matlab程序实现对裂隙方向数据的自动提取、玫瑰花图绘制、裂隙方向分组及裂隙分布函数的拟合。最后,对贵州省普定实验站的典型裂隙剖面的应用结果表明,该实测剖面的裂隙方向服从正态分布,且裂隙按隙宽分类得到的4种类型裂隙与整体裂隙的玫瑰花图、分布函数基本一致,增进了对裂隙方向统计分布的认识。 The fracture orientation of rock mass is the breakthrough of fracture geometry description. The fracture rose diagram is one of the main expression of directional statistical data. In the past, most of them were drawn by manual statistics, and the efficiency was very lower. According to the fracture space, fractures were divided into four types of large, medium, small and tiny for the typical fracture profile of the Puding Experimental Station in Guizhou Province. And ArcGIS and Matlab program were used to realize automatic extraction of geological data, automatic drawing rose diagram, and the grouping of fracture orientation and the fitting of the fracture distribution functions. Finally, the application results show that the fracture orientation of the measured section obeys the normal distribution. Moreover, the rose diagram and distribution function of the orientations of the four types classified by fracture aperture are basically consistent with that of the whole fracture. This study helps to improve the understanding of the distribution law of the fracture orientation.
