Discarded tires used as reinforced materials have distinctive merits, such as high tensile strength, good anti-friction, fine flexility and durability, which can be used in reinforced wall, embankment and slope etc. some successful applications of discarded tire in reinforced slope are introduced, which have not only obtained significant economic benefits, but also resulted in good social and ecological benefits. The environment stress resulted from the world black pollution of discarded tires may be relieved through these new geotechnical applications. Different reinforced pattern of discarded tires are compared. The result has shown that discarded tire used for reinforcement is a particularly useful method. The settlement need to be given attention during reinforced engineering. Clay soil is averted as reinforcement with discarded tires. The tire with inside wall removed and backfilled with sandy soil is a good reinforced pattern.
