LANDSLIDE PREVENTION PILE AND DESIGN METHOD THEREOF
To provide a landslide prevention pile capable of reducing steel weight and construction cost when designing with restraint piles and a design method thereof.SOLUTION: The landslide prevention pile is a landslide prevention pile for preventing a landslide where a moving-bed 1 above a slide surface 5 slides along the slide surface 5 with respect to an immovable layer 3 below the slide surface 5 with the slide surface 5 in the ground as a boundary. The landslide prevention pile is a steel pipe pile 7 which is a restraint pile, and the allowable stress σa of the steel material forming the steel pipe pile 7 and the rigidity EI of the steel pipe pile 7 satisfy a specific equation.SELECTED DRAWING: Figure 1
【課題】くさび杭で設計される場合に、鋼材重量を低減して建設コストを抑制できる地すべり抑止用杭およびその設計方法を提供する。【解決手段】地すべり抑止用杭は、地中のすべり面5を境にして、すべり面5より下方の不動層3に対して、すべり面5より上方の移動層1が、すべり面5に沿って滑る地すべりを抑止するための地すべり抑止用杭であって、地すべり抑止用杭はくさび杭である鋼管杭7であり、かつ鋼管杭7を構成する鋼材の許容応力度σaと鋼管杭7の剛性EIが特定の式を満たすものである。【選択図】図1
