    • Abstract
  • The collapse disasters are easily caused by the cut of fissures in gently inclined bedding rock mass slopes. The complex gently inclined bedding rock mass slope containing two fissures is studied. At first, based on the fracture mechanics and the mechanics of materials, a method for calculating the load and stability coefficient of complex gently inclined bedding rock mass slopes is established. For the case of Yangchahe gently inclined bedding rock mass slope in Qijiang County of Chongqing, the slope stability is calculated, and the results are the same as the field damage situations. Then the stability coefficient of the gently inclined bedding rock mass slope is obtained through numerical simulation. The numerical results are the same as the calculated ones. The numerical results reveal the damage mode and rules of Yangchahe gently inclined bedding rock mass slope. The compressive stress is the main factor for the damage of rock cells. The proposed method for the load and stability coefficient of complex gently inclined bedding rock mass slope may provide a theoretical basis for the design and layout of the relevant control structures.
