摘要： PROBLEM TO BE SOLVED: To prevent flowing-down to a lower section from the mountain side of soil and sand on a ground surface of the face of a slope, to which a method of slope stabilization construction is executed. SOLUTION: Bearing-pressure members 1 are installed at the upper end sections of a plurality of anchor rods 5 driven to the face of a slope 8a at intervals respectively, nuts 7 are clamped and tensile force is applied to the anchor rods 5, and the tensile force is transmitted to the face of the slope through the bearing-pressure members 1 and the face of the slope is stabilized. Beltlike netted members 10 are stretched at right angles with the face of the slope among the two bearing-pressure members 1 arranged in the horizontal direction. Even when soil and sand on a ground surface intend to flow down from the mountain side to a lower section owing to the inclination of the face of the slope 8a, the netted members 10 stop soil and sand. Not only a slope ground is stabilized by a bearing-pressure effect by the bearing-pressure members 1 but also the flowing-down of soil and sand on the ground surface can be prevented.
