Abstract
In order to find out the sensitivity of influencing factors on the slope stability of geogrid reinforced tailings dam, the single index multi factor numerical simulation test was designed by orthogonal method, Five influencing factors including elastic modulus (E), laying length (L), laying spacing (d), pseudo-cohesion of reinforcement-tailings interface (cif) and pseudo friction angle of reinforcement-tailings interface(φif) were selected .The L25(56) orthogonal table 25 groups of scheme was designed, numerical calculation was carried out by finite element strength reduction method to determine the safety factor and analyze the sensitivity of factors affecting the stability of stiffened tailings dam.The results show that the order of sensitivity of influencing factors of reinforced tailings dam is laying length (L) > laying spacing (d) > elastic modulus (E) > pseudo-cohesion (cif) > pseudo friction angle (φif); The significance test results show that the laying length (L) and laying spacing (d) have a very significant impact, the elastic modulus (E) and pseudo-cohesion (cif) have a significant impact, and the pseudo friction angle (φif) the impact is not very significant; Among them, the sensitivity ranking of reinforcement influencing factors of range analysis results is consistent with the significance results of analysis of variance, which verifies the reliability of numerical simulation results.
