Abstract

In order to find out the sensitivity of reinforcement factors that influences the geogrid reinforcement on slope stability of mine tailings, this paper designs the test according to orthogonal method. By choosing laying length (L), laying distance (D), laying angle (θ), tensile strength (T) and geogrid modulus (E) as influential factors and adopting the L25(56)orthogonal table for 25-group scheme arrangement, this test tries to get corresponding safety factor (F) of the reinforced slope through the strength-shear method with finite elements and make analysis on both the sensitivity and the significance of all available factors separately via variance analysis. The results show the sensitivity of all influential factors on stability and safety factor as follow in order of most to least: laying distance (D), tensile strength (T), geogrid modulus (E), laying length (L), laying angle (θ). the remarkable test show that laying distance (D) and tensile strength (T) both have very remarkable influence and geogrid modulus (E) comes second, while laying length (L) only shows a little and laying angle (θ) little.
