equilibrium method (LEM) integrated with the unsaturated soil mechanics concepts. Results revealed that the combined use of the primary and secondary geotextile reinforcements significantly improves slope stability by mitigating shear stresses near the slope face, reducing shallow failure surfaces, and ensuring global stability. Drainage-enabled geotextiles were particularly effective, facilitating rapid dissipation of pore pressure, lowering the phreatic surface, and achieving a higher factor [...] Global warming has intensified erratic climatic events, such as increased rainfall, flooding, and rapid drawdown, often triggering slope failures. This study investigates the influence of primary and secondary geotextile reinforcements on the stability of unsaturated soil slopes under rapid and transient drawdown conditions. Seepage forces were analyzed using the effective stress B-bar method and finite element method (FEM), while slope stability was assessed using the limit equilibrium method [...] Under a Creative Commons license

test. Slope stability analyses should account for interface shear strength along a geocomposite drain. The geocomposite/soil interface will most likely have a friction value that is lower than that of the soil. Thus, a potential failure surface may be induced along the interface. Geotextile reinforcements (primary and intermediate layers) must be more permeable than the reinforced fill material to prevent a hydraulic build up above the geotextile layers during precipitation. Special emphasis on [...] or uniaxial) and geotextiles. These reinforcements are a wrapped face consisting of a layer of geogrid that wraps around the face and a layer of geotextile to prevent erosion of the reinforced soil materials.

### Reinforcement
Woven geotextiles and geogrids add tensile strength to the soil mass, distributing applied loads and improving shear resistance. On soft or weak soils where a slope cannot support its own weight, reinforcement is the primary function. High-strength geogrids used in Geosynthetic-Reinforced Soil (GRS) walls and slopes are designed to deliver this tensile capacity with low strain and a high bond coefficient with soil.
### Filtration and Pore Pressure Relief [...] Nonwoven geotextiles are produced by bonding fibers together — through needle-punching, thermal, or chemical processes — rather than weaving them. Key properties include high permeability, flexibility, and excellent filtration capability, which make them the preferred choice for drainage relief, filtration, and surface erosion control.
Weight selection matters on slopes with varied soil conditions: [...] Geotextile fabric for slope protection is a permeable synthetic or natural material installed on or within a slope to control erosion, reinforce soil, and manage water movement. Depending on the product, it functions as a filter, reinforcement layer, separator, or surface cover — preventing soil loss from rainfall, runoff, and gravity.

design guidelines for GRSS. The existing topography, subsurface conditions, and soil properties must be considered when evaluating the site for construction. The investigation should include determining the availability of the required type of reinforced fill and backfill materials. 3. Geogrid or geotextile constructed of polyester, polypropylene, or polyethylene are recommended for soil slope reinforcement. The material should be resistant to heat, ultraviolet light, attack by bacteria and [...] recommended the use of geogrid or a combination of geogrid and geotextile for slope reinforcement, while the others recommended independent use of geotextile. Some prefer high strength geotextiles over geogrids, as they provide a separation function and can be more cost effective in certain cases. Figure 2. Recommended Design Methods. The internal stability of a soil slope can be determined by four basic factors, including the slope angle (β), soil weight (W), cohesion (c), and internal [...] (γu) = 125 lb/ft3 Reinforced Soil: Internal Friction Angle (ϕrʹ) = 34° Cohesion (crʹ) = 0 Density (γr) = 125 lb/ft3 Depth of Water Table (dw) = 5 ft Figure 36.

Reinforcement is one of the core functions. Relying on its excellent tensile strength (the longitudinal tensile strength of synthetic fiber geotextile can reach 25–50kN/m), geotextile forms a geotextile-soil composite structure with the soil, dispersing the local load borne by the soil to a wider range. This effectively improves the soil’s shear and deformation resistance, and reduces subgrade settlement and slope displacement. In soft soil foundation projects, it can increase the soil [...] Protection extends the service life of the stabilization system. Geotextile can buffer the impact of external loads, block the puncture damage of sharp particles to the soil, resist rain erosion and chemical corrosion, and protect the integrity of the soil structure. In scenarios such as riprap slope protection and retaining wall backfilling, it can effectively reduce soil erosion and extend the service life of the project by 10–15 years. [...] Case: In a mountain slope protection project (slope gradient 50°), woven geotextiles were combined with vegetation slope protection. The geotextiles achieved soil separation and auxiliary reinforcement, and the vegetation roots penetrated into the soil to form an ecological stabilization system, effectively avoiding landslide risks. Meanwhile, it met the requirements of ecological restoration, suitable for mountain infrastructure projects.

Woven geotextiles are manufactured by interlacing yarn or tape in a structured grid pattern, giving them high tensile strength and low elongation — properties required for soil reinforcement and load transfer in slopes and embankments. Non-woven geotextiles are needle-punched or thermally bonded and have higher permeability and filtration capacity but lower tensile strength. For slope reinforcement and embankment stabilisation, high strength woven geotextile is the correct specification; [...] #### Conclusion

may involve a low-height steep slope that may not need a stone wall support as shown in Figure 1. In such cases, the slopes can be reinforced with geosynthetic layers (geotextile or geogrid), to improve the stability, defined in terms of factor of safety F to an acceptable value. Geosynthetic layers have proven to be effective and economical in improving the mechanical properties of soils, and moreover, they allow to construct environmentally friendly and sustainable structures (Shukla et al.
