Abstract

The application discloses a soft and hard interbedding type anti-inclined rock slope stability rapid analysis method based on a superimposed cantilever beam model and belongs to the technical field of rock slope stability analysis. The method comprises the following steps: soft and hard interbedding type anti-inclined rock slope calculation parameters are drafted; two adjacent soft and hard rock layers are regarded as a unit, and the characteristic height of the soft and hard interbedding type anti-inclined rock slope rock layer is determined; in combination with the characteristic height, a soft and hard rock layer superimposed cantilever beam model is established, stress analysis is respectively conducted on the soft and hard rock layers, the safety factor of the soft and hard rock layers is calculated; the stability of the soft and hard rock layers is compared, the rock layer damage sequence is considered, the influence of rock layer damage on the internal force and stability of the soft and hard rock layers is analyzed; the safety factor of the soft and hard interbedding type anti-inclined rock slope is obtained, and the overall stability of the slope is evaluated. The method can quickly evaluate the slope stability by establishing the soft and hard rock layer superimposed cantilever beam model, and the calculation method is simple.
