| 摘 要： | 给出了岩石破坏后侧向应变与纵向应变之比与围压之间的定量相关关系，并利用霍克－布朗（Ｈｏｃｋ－Ｂｒｏｗｎ）的节理岩体经验强度准则，推导出了考虑岩石破坏后变形特性的巷道围岩特征曲线方程，并给出了一个工程算例。结果表明，理论结果与实测结果比较吻合。

| Abstract: | The relationship between the ratio of the lateral strain and longitudinal strain and the confining pressure is established.With Hoek-Brown empirical failure criterion for joint rockmass,the authors present the solutions of ground response curves by taking the deformation characteristics of broken rock into consideration Finally , verification of the theoretical analysis results is made with a engineering example of Xieqiao Colliery. |
