Study on georid reinforced stone

Systematic tests are made for the geogrid reinforced stone. The results show that the stress strain condition of geogrid reinforced body, distance of geogrid interlayer and stone properties are of important factors of reinforcement. The stone strength is obviously increased and its deformation is decreased by reinforcement. Mechanism of geogrid reinforced stone is in accord with pseudo cohesion concept. Tensiomembrane reaction is effective only under some special conditions.
