Abstract

The overland flow on the steep side of the slope caused landslides on the road section of Bts. Riau – Bts. Payakumbuh STA 200+500, West Sumatra. To overcome the landslides that occured and prevent the occurrence of secondary landslide that can worsen the condition of the road, an alternative reinforcement that can withstand the slope landslide is needed. In this study, an alternative reinforcement of soil nailing and geogrid is used. Soil nailing reinforcement used consists of 10 nails with uniform vertical and horizontal depth of 0,5 m. The length of each nail is 6 m, with a nail diameter of 19 mm and a bore hole diameter of 150 mm. While for geogrid reinforcement that used consists of 7 layers with a uniform geogrid depth each layer of 8 m. The vertical depth between the geogrid layers has 2 types, namely 0.5 m and 1 m with the geogrid type of GX 200/50 and ultimate tensile strength of 200 kN / m. Based on the slope stability analysis carried out with Plaxis, the safety factor of unreinforced slopes is 0.769. Whereas, slope safety factors with alternative reinforcement of soil nailing and geogrid generate slope safety factor of 1.584 and 1.558 which qualify slope stability requirements.
