To provide a wire-system slope method capable of eliminating the fragility of a joint part by a binding wire of reinforcement such as a usual prestress concrete or the like, also decreasing site work by welding of the reinforcement or the like and preventing partial or overall destruction of a slope in a slope stability method.

A slope reinforced method forms a grid slope protection making a wire rope without restriction on the length resulting from conveyance or the like and a wire for binding fine steel wires (binding wire) or the like as a reinforced material. The binding wire 110 is placed at a certain distance from the slope 700 in anchors 610, 620, 630, 640 and 650. The anchor 610 can be driven into a position having the strong ground separated from the slope 700. A heavy substance can be also added to the lower end of the binding wire 110.
