Research on Geosynthetics in Tailings Dam Reinforcement

With the tailings dam reinforcement project newly built in Yakou as the example and limit equilibrium horizontal slice method as the methodology, this paper has researched the feasibility of applying geosynthetics in fine tailings dam reinforcement. The results from limit equilibrium horizontal slice method show that the stability of reinforced tailings dam with geosynthetics increases by 14 similar to 17%; while results from numerical simulation method show that the principal stress vector direction and the principal displacement vector direction of the dam body can be changed to be favorable to the stabilization of dam by using geosynthetics to reinforce the tailings dam.
