Abstract
Aiming at the optimization problem of internal dumping pressure side of the combined slope,the article uses the limit equilibrium analysis method to check the slope stability before the pressure side,and analyzes the variation law of the slope stability coefficient under different pressure side heights.The article optimizes the design scheme of the dumping pressure side according to the minimum dumping amount,and determines the final dumping parameters.The research conclusions show that the combined mining area is the main sliding area of the slope.The height of the pressure side affects the sliding form of the slope.When the height of the pressure side is insufficient,it is easy to form a sliding along the merged step.Under the same height of the pressure side,the wider the flat plate is,the higher the stability of the slope is.The final dumping pressure height is 75 m,the uppermost is 15 m steps,and the lower part is a two-stage 30 m step.关键词
