Method of construction for stability

PURPOSE: An environmentally-friendly stabilization method of a composite slope is provided to rapidly stabilize a slope which does not have a failure plane by filling the inside a fiber form with high-fluidity mortar. CONSTITUTION: An environmentally-friendly stabilization method of a composite slope is as follows. A failure plane(10) of a slope is grinded in a stair shape. Multiple boreholes(31) are formed by boring the grinded failure plane. Stiffeners(40) are inserted into the boreholes. The boreholes are filled with high-fluidity mortar(50). The failure plane is reinforced using environmentally-friendly lightweight mortar(60). A fiber form is spread on the slope. The inside the fiber form is filled with high-fluidity mortar. A reinforcement member is connected to the fiber form filled with the high-fluidity mortar.
