摘要
构造了一台无初始节理和一套有初始节理的岩体采动沉陷相似材料模型，进行模拟开挖实验，系统研究初始节理对岩体采动沉陷的影响规律，然后运用损伤力学理论研究节理在岩体采动沉陷中的作用，建立了地表移动特征值与岩体损伤变量的经验关系．
In this paper, two simulated material models, one contains some initial joints and another contains no initial joints, are employed to investigate systematically the influence of initial joints on the surface subsidence. Moreover, within the framework of damage mechanics,the influence and effect of initial joints on the surface subsidence are investigated, and the empirical relation between the characteristic value of surface subsidence and damage variable is obtained.
