摘　　要：采用蒙特卡洛(Monte-Carlo)模拟方法和数字图像处理技术,编写岩体内部微裂隙模拟分析软件。利用该软件提取出岩体中的微裂隙并获得微裂隙长度、方位角、间距等信息,最后通过进行统计分析模拟生成微裂隙的分布情况。实践证明,该方法能较真实地反映岩体内部微裂隙的特征及分布规律,为进一步进行三维模拟及损伤演化分析等提供信息。The simulation analysis software on internal microfracture of rock mass was written by Monte-Carlo simulation method and digital image processing.Microfracture in rock mass was extracted and its length,azimuth angle,spacing and other information were obtained by this software.Finally,the distribution of microfracture was simulated by statistical analysis.Practice proved that this method could truly reflect the characteristics and distribution of internal microfracture, which further provided information for threedimensionalsimulation and damage evolution analysis.
