本文对单节理岩体在真三轴压缩状态下的强度特性进行了分析，重点讨论了中间主应力对单节理岩体强度特性的影响诸问题．研究认为，中间主应力对节理岩体的强度特性是有影响的，在一定条件下，甚至可以成为主要的影响因素．
In this paper, the strength characteristics of single jointed rock mass under true triaxial compression are analyzed, and the problems of the influence of intermediate principal stress on the strength characteristics of single jointed rock mass are discussed. The study suggests that the intermediate principal stress has an impact on the strength characteristics of jointed rock mass and may even become the main influencing factor under certain conditions.
