Abstract: In order to avoid the shortcomings of current reinforcement method for geosynthetic materials， a type of reinforcement method， named an end scroll geosynthetics that both the start port and the end port of geosynthetics were rolled in reinforcement， was introduced. Its function principle and advantages were also analyzed. And with the new tailings dam reinforcement project， the feasibility of using the reinforcement method of end scroll geosynthetics in the tailings dam was analyzed by horizontal slice method and numerical simulation method. The results show that after using the reinforcement method of end scroll geosynthetics， not only the stability can be increased by 14%~17%， the stress distributions are also changed toward the favorable direction to dam stability.

Key words: tailings disposal, end scroll geosynthetics, slope stability, numerical simulation
