岩体结构面连通率研究进展及应用

岩体结构面连通率的研究一直是岩石力学研究领域的难点之一。一些学者已经相继提出了多种确定连通率的方法，但许多方法可能引起的误差较大，实用性也较差。广义H—H连通率公式和基于网络模拟的计算方法是近年发展起来的比较成熟且实用的方法。文章评述了各种方法的适用性和有效性，并采用基于结构面网络模拟的“带宽投影法”进行了实例分析，最后讨论了岩体结构面连通率的研究趋向。

Development of Research of Connectivity Rate of Discontinuities in Rock Mass and Application

The research of connectivity rate of discontinuity in rock mass is always one of the difficulties in the field of rock mechanics. Some scholars have put forward several methods to confirm the connectivity rate. But many of them may lead to quite big error, and they are not practical. The formula of broad sense H-H and the method based on network simulatiun are excellent methods emerged in recent years. The fitness and validity of all these methods to calculate connectivity rate are recounted and commented on in this text. The bandwidth projection method based on network simulation is used to calculate the connectivity rate for one example. At last, the tendency of the research of discontinuity in rock mash is prospected.
