| 摘 要： | 介绍了面连通率在岩体破坏研究中的表述方法。连通率的大小可反映破坏概率的大小。选择可能滑动面进行连通率计算方法有：多个结构面组成的折面；单个结构面的扩展面。两种面连通率均反映了在空间平面上结构面的发育程度，揭露更多隐藏的破坏性信息，有利于定量、定位分析岩体稳定性。

| Abstract: | The concept and calculation method of connection rate of discontinuity on plane are presented in this paper The value of connection rate indicates the rock mass failure probability Probable slide face used by calculating connection rate may be zigzag plane of many discontinuities or extension plane of single discontinuity These two connection rates of discontinuity on plane reflect the discontinuity development on spatial plane,reveal more concealed failure information and may be taken advantage of analysing rock mass stability quantitatively and localizably. |
