The results of a series of plane strain model loading tests of footing on both reinforced and unreinforced sand slope made of a fine quartz-rich sand, Toyoura sand, performed under well-controlled loading conditions are described. It is shown that the bearing capacity of footing can be increased very efficiently by introducing stiff reinforcing strips into the vicinity of active wedge which occurs in the corresponding unreinforced slope. It is also shown that both the bearing capacity characteristics and the failure patterns of reinforced slopes largely depend on the arrangement of the reinforcement members. The failure pattern of the model slopes are classified into four types. The subsequent stability analyses by using various limit equilibrium methods will be presented in the companion paper, which will appear in the near future.
