岩体变形是表征岩体力学作用的重要方面之一。实验资料表明,坚硬的碎裂岩体变形可分为两个阶段,即在低应力水平条件下以结构面闭合为主的压密变形阶段;在高应力水平条件下则以结构体弹性变形为主的压缩变形阶段。因此,应 Rock deformation is one of the important aspects of the mechanical behavior of rock mass. The experimental data show that the deformation of hard and broken rock mass can be divided into two stages, that is, the compaction and deformation stage dominated by the closure of the structural surface at low stress levels, and the elastic deformation of the structure at high stress levels. The main stage of compression deformation. Therefore, it should be
