Mechanics of Reinforcement–Slope Interactions

Steepening of slopes for construction of rail/road embankments or for widening with geosynthetics for other civil engineering structures is a necessity for development. The present paper details a kinematic analysis to optimize the length of geosynthetic reinforcement from the face or near end of the slope with respect to its location to obtain the desired minimum factor of safety. Unreinforced and reinforced slopes are analyzed using Morgenstern–Price method to obtain critical factors of safety. The effect of providing geosynthetic reinforcement layer in shifting the critical slip circle has been identified and quantified. The length of the reinforcement is optimized by curtailing the superfluous length from face end but maintaining the required factor of safety.
