(Sun and Zhao 2013, Seward et al. 2011) to develop stability charts. The slope stability modelling was conducted by adopting the Morgenstern-Price method of analysis, auto-locate critical slip surface search technique, Mohr-Coulomb soil model and reinforcement fabric option in the software. Details on the modelling process has been discussed by Baah-Frempong and Shukla (2018) Based on the model validation carried out by Baah-Frempong and Shukla (2018) using data reported by Zonberg et al. [...] 2. Slope geometry, reinforcement layout and soil parameters used in the study: (a) 40°, 50°, 60° unreinforced slope; (b) 40° reinforced slope; (c) 50° reinforced slope; (d) 60° reinforced slope. 3. STABILITY ANALYSIS AND DEVELOPMENT OF DESIGN CHARTS The stability analysis of the slopes presented in Figure 2 (a-d) was carried out using the limit equilibrium method (LEM) provided in a commercial software, Slope/W. It should be noted that Slope/W has also been used by other researchers (Sun and [...] to provide adequate slope stability. Michalowski (1997) analyzed the stability of slopes with geosynthetic layers installed at equal vertical spacing throught the slope height. The investigation produced design charts that can determine the required reinforcement strength and length to prevent slope failure. Zhu et al. (2014) prepared charts for quick assessment of the stability of stacked geotextile tubes. The charts allowed the factor of safety to be evaluated base on the slope geometry and

developed between geotextile and soil and placing pattern of reinforcements. Koerner (1990) provided analysis method of geotextile-reinforced slopes for c-soil using limit equilibrium concept. Mandal and Labhane (1991) carried out studies on geotextile-reinforced slopes. Lengths of geotextile in the top and bottom portion of the slope were varied for various slope inclinations and soil properties. It was noticed that for steeper slope the length of geotextile for top layer was kept higher as [...] and validate finite element methods. Bergado et al. (2002) conducted stability analysis of embankment with and without reinforcement using PLAXIS 2D and concluded that single layer of high-strength geotextile (HSG) increases the critical slope height up to 1.5 times higher than that of the unreinforced case. HSG can significantly reduce vertical as well as horizontal displacement during plastic analysis. Zornberg and Arriaga (2003) conducted digital image analysis and centrifugal testing to [...] Sequential construction method was adopted during analysis process in which whole soil strata was divided into 7 stages. During analysis of stage 1 only bottom most geotextile layer i.e. G1 was kept active, while for stage 2 bottom two layers were kept active (i.e. G1 and G2). Likewise similar fashion was adopted for remaining all stages. The trend capture for development of axial force for the slope inclination () 45 was almost same. As the slope inclination increase, the maximum

Analysis Figure 20. External Stability Analysis of Geosynthetic Reinforced Steep Slopes (Berg et al., 2009). The analysis performed in Step 5 should provide the factor of safety for failure surfaces behind the reinforced soil zone. However, as a check, classical rotational slope stability methods such as Bishop (1955), Morgenstern and Price (1965), Spencer (1967), or others may be used. Appropriate computer programs may also be employed. To determine local bearing failure at the toe (lateral [...] Geotextile Design Method: Static and seismic slope stability analysis. Construction Sequence: The installation of wire mesh was found to be straightforward. This ensured that the construction tolerances required for the face were easily met and the work was completed within the tight construction period. Polyamide matting was used a surface erosion control blanket at the toe of the slope and geotextile was used as a separator between the rock facing and the reinforced backfill. Cost [...] for GRSS being 1H:1V (45°) and 1H:2V (63°). Although geosynthetic reinforcement can also be used for structures with a geometry of 1H:3V (72°) or steeper, other stabilization elements may be needed to prevent erosion of the face. Figure 32. Height and Angle of Geosynthetic Reinforced Steep Slopes. 63 DESIGN METHODS Slope stability analysis was performed utilizing the FHWA design guidelines for many of the case studies in order to evaluate the GRSS. This process is based on global safety factors

The correct geosynthetic reinforcement must be determined to meet both long-term strength and soil interaction requirements. Failures commonly occur at interfaces, especially where geotextile and soil interact. Therefore, a stability analysis can evaluate the compatibility of the slope with a geosynthetic material as well as ensure the safe design of a slope. [...] Slope stability analysis accomplishes four key objectives: it determines the long-term survivability of existing and excavated slopes, evaluates the effectiveness of proposed reinforcements, calculates shear strength and designs a successful slope.
## Conducting Slope Stability Analysis [...] The geometry of the slope, incorporated materials, soil, environmental (soil gasses) and geological forces (seismic and groundwater) are only a few of the factors to consider in determining slope stability. A careful analysis can assess the likelihood of sliding or collapse of the slope, its impacts and proper reinforcement techniques.

Main options include geotextiles, erosion control blankets, geogrids, vegetation and hydroseeding, retaining walls, soil nailing, riprap, and geocells. Geotextiles are often combined with these methods — as a filter layer beneath riprap, for example, or as reinforcement within a vegetated embankment.
### What type of geotextile fabric is best for slope stabilization and drainage? [...] 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.
### What are the options for slope stabilization? [...] Geotextiles address multiple failure mechanisms at once: reinforcing soil, controlling drainage, protecting exposed surfaces, and separating dissimilar materials. Engineers, contractors, and municipalities across Iowa use them on everything from highway embankments to riverbank revetments.
This guide covers the main types of geotextile fabric, how they stabilize slopes, how to choose the right product, installation best practices, and common applications.
