Zusammenfassung:PROBLEM TO BE SOLVED: To provide a falling stone protective facility capable of sustaining excellent damping performance by suppressing the occurrence of cracking. SOLUTION: This falling stone protective facility is structured by forming a damping dam body in the rear of a retaining wall also serving as a form and placing a received impact distribution layer on the upper surface of the damping dam body. The damping dam body is formed of a foamed lightweight soil which is formed mainly of sediment and to which short fibers are mixed. A damping insulation layer pre-attached to the rear surface of the retaining wall is interposed between the retaining wall and the damping dam body to insulate the damping dam body from the retaining wall.
