| 摘 要： | 岩体中裂隙的分布是研究岩体内部渗透性和岩体稳定性的关键。自然界存在的交错分布的岩体裂隙可以看作为一种网络形态,从此观点出发,应用复杂网络理论中相关参数对这种裂隙网络进行了分析。分析结果认为,岩体裂隙网络拥有较小的平均最短路径长度和较大的集聚系数,也就是说,裂隙网络表现出小世界特性。对于分析岩体裂隙的渗透性或者浆体移动规律等具有辅助作用。

| Abstract: | The distribution law of fracture in rock mass is the key to study rock permeability and engineering stability.Rock fractures of staggered distribution which exist in nature can be looked as a kind of network.Based on this view，the fracture networks are analyzed by using complex network theory with relevant parameters.The results showed that rock fracture networks owned low average shortest path-length and high clustering coefficient.In other words，rock fracture networks appear the properties of “small-world”.The results have an auxiliary effect on analyzing rock permeability and magma displacement law. |

| Keywords: | Rock fracture Small-world network Clustering coefficient Average shortest path-length |
