Three-Dimensional Analysis Method for Stability of Toppling Rock Slope
The present invention belongs to the field of stability analysis of rock slopes, and particularly relates to a three-dimensional analysis method for stability of a toppling rock slope. The method includes: defining a toppling body, and dividing the toppling body into blocks to establish a block system, wherein the block system includes at least one block; establishing a force balance equation and a moment balance equation of the block; and establishing a standard optimization model by using the force balance equation and the moment balance equation of the block as constraint conditions, and calculating a slope stability safety factor of the toppling body through the standard optimization model. In the present invention, on the basis of force and moment balance equations, under the constraint condition that the boundary satisfies a yield condition inequality equation and with the maximum value of the slope stability safety factor as an objective function, the three-dimensional analysis of the stability of the toppling rock slope is converted into a optimization solution problem, thereby reducing errors and being beneficial to better reflect the mechanical characteristics and the stability characteristics of the three-dimensional analysis of the stability of the toppling rock slope.
