DEBRIS FLOW PREVENTION STRUCTURE
To dam a debris flow that occurs in a mountain stream where the debris flow is expected to occur, while mitigating the impact that the structure receives from the debris and preventing the structure from collapsing when a tensile material (cable) is used in combination.SOLUTION: A debris flow prevention structure 1 is composed of a structure 2 constructed three-dimensionally on a riverbed, and a tension member 15 that is installed between the structure 2 and the ground on both banks of the river so that ends on both banks are fixed to the ground and that, together with the structure 2, bear the impact force from debris when a debris flow occurs. The structure 2 is composed of multiple lower frame members 3 arranged in parallel in the width direction of the river on the riverbed 30, front vertical frame members 4 and rear vertical frame members 5 that are joined to the upstream and downstream sides of the axial direction of each lower frame member 3 and stand up from the lower frame members 3, and connecting members 61, 62 that are installed between the lower frame members 3, 3 adjacent in the width direction of the river and connect them to each other. The tension members 13 are arranged in two or more stages in the height direction of the structure 2.SELECTED DRAWING: Figure 1
【課題】土石流の発生が想定される渓流に発生した場合の土石流を堰き止める上で、構造体が土石から受ける衝撃を緩和させつつ、引張材（ケーブル）を併用する場合の構造体の転倒を防止可能にする。【解決手段】渓床上に立体的に構築される構造体２と、渓流両岸の地盤と構造体２との間に架設されて両岸側の端部が地盤に定着され、土石流の発生時に土石からの衝撃力を構造体２と共に負担する引張材１５から対土石流構造物１を構成し、渓床３０上に、渓流の幅方向に並列して配置される複数本の下部枠材３と、各下部枠材３の軸方向の上流側及び下流側に接合され、下部枠材３から起立する前方側縦枠材４及び後方側縦枠材５と、渓流の幅方向に隣接する下部枠材３、３間に架設され、両者を互いに連結するつなぎ材６１、６２から構造体２を構成し、引張材１３を構造体２の高さ方向に２段以上、配置する。【選択図】図１
