B. facing system. The design process must address all possible failure modes that a reinforced (or unreinforced) slope would potentially experience. Other reinforcement and stabilization applications in which geosynthetics have also proven to be very effective include roads and railroads, large area stabilization and natural slope reinforcement. INTRODUCTION The conventional method of embankment dams to a stable slope for a given height may involve considerable expenses in material, plant, construction time and extension to the base area of embankment dam. The primary reinforcement spacing in GRS is equal to 8 in. elevations. Geotextile bags gabion is cost-effective and can resist to erosion using in river bank and channel, slope reinforcement and greening. By the angles of the surcharge slope… Protect ground surfaces (especially slopes) from loss of soil due to water Temporary erosion mats are used for flatter slopes (<45o) and degraded after development of vegetation (i.e., Erosion-control blanket) Permanent erosion mats are used for steep slopes (>45o) (i.e., Turf Reinforcement Mat) Slope angles can be increased and 'poor' soil can be used to construct economical soil-geosynthetic facilities. Shear stress acts between the bank and the soil underneath due to lateral soil pressure on the bank. Q2. References 17 7.Appendix Koerner A2 VanZanten A8 Polyfelt A13 Ingold A17 Tensar A21 Jewel1etal A24 Bonaparteetal A28 VerduinandHoltz A32 LeshchinskyandPerry A45 The load was applied through a 190.5-mm diameter steel plate. Slope angles can be increased and 'poor' soil can be used to construct economical soil-geosynthetic facilities. Two geotextiles were used: a nonwoven polyester geotextile with a strength of 22kN/m and a woven polypropylene geotextile of 22kN/m. geosynthetic-reinforced slopes (Zornberg et al. Summary 16 6.
