Design and Simulation of Natural-Slope Reinforcement using Non-Frame Method: A Case Study in Davao City, Philippines

Slope failure happens when the shear resistance along the slip plane is exceeded which could result in landslides.This study aims to provide a design and simulation of natural-slope reinforcement as the solution to prevent such hazards.Using Non-Frame Method, also known as Soil Nailing method is a practical approach for it is cost efficient, environmentally friendly and does not require deforestation.Soil Nailing uses passive bars that can withstand tensile and shearing forces as well as bending moments.A geo-technical software is used to evaluate the intersection points between soil nails and possible slip surfaces that will help achieve the appropriate design.The calculated factor of safety is equivalent to 1.84 which is greater than the design factor of safety for slope stabilization used in the Philippines while using the allowable tensile strength of the full-threaded steel bar reinforcement to the slope.
