Abstract:
      The bedding rock slope is affected by natural geological structure and its stability is relatively poor. However, under the influence of strong degradation factors such as heavy rain, blasting and earthquakes, its stability is more threatened. Therefore, based on the strength reduction theory, this paper analyzed the stability of the bedding rock slope of a mine by numerical simulation. Meanwhile, this paper studied the position of the sliding surface of the rock slope, the lateral deformation and the stress change law of the rock slope under the bedding design and two optimization schemes under the three conditions of heavy rain, blasting and earthquake. The research results indicated that: the earthquake had the greatest impact on the stability of the bedding slope of the mine; in addition, the safety factor of the slope under the conditions of the proposed design scheme was lower than the standard value, and the slope was in an unstable state. Through the optimization study of the bedding slope of the mine, the optimal design plan of the mine was obtained.
