Abstract
Crib wall is one type of retaining wall that is often done for slope reinforcement. Usually made of pre-cast concrete beams mounted interlocked-hooks with considerable construction costs. Based on that it is necessary to research the construction of slope reinforcement with low cost and easy in its implementation. The purpose of this research is to design crib wall by utilizing the local material. The research location is the slope of Trans Sulawesi-Pantai Selatan Street, precisely the slope of the road in Muara Bone Village (Bone Subdistrict) and Oluhuta Village (Kabila Bone Subdistrict), Bone Bolango Regency. Crib wall material used is timber obtained from around the research area. Slope stabilization analysis was performed using limit equilibrium with the help of Slide3 2017. The results of external and internal stability analysis showed that the slopes with the construction of timber crib walls in stable condition (Factor of Safety, FS>1.5). It is expected that the crib wall model can be an alternative to stabilize the roadside slopes in Bone Bolango District, due to the cheaper construction cost compared to other conventional retaining wall construction.
