(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. [...] following problem: Determine the factor of safety of a reinforced and unreinforced sandy soil slope with β=50°, γ=16.5 kN/m3, c’=1 kPa, ϕ’=33°, and H=3 m 4.1 Solution It is first required to calculate the stability number, N=c’/γHtan ϕ’ . For this case N=0.03. Using the calculated N value and the stability charts presented in Figure 3 (a-b), the factors of safety for the unreinforced and reinforce slopes are calculated to be 0.85 and 1.25, respectively. It is shown in this analysis that [...] Salih Keskin and Laman 2014). The outcome of these research has established that reinforcing slopes with geosynthetic layers significantly improves the bearing capacity of the footing and reduces settlement. The literature shows that there is a limited study on the stability analysis of reinforced slopes that are not subjected to footing loads on the crest. A typical application of the outcome of such investigations is landscape works. Mehdipour et al. (2013) investigated the stability of

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 [...] a higher factor of safety (1.790) compared to non-drainage geotextiles (1.439). These findings highlight the dual role of geotextiles in providing reinforcement and drainage, confirming their potential as a sustainable solution for mitigating slope failures during rapid drawdown in the face of climate uncertainty.

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.

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 [...] Slope stability analysis should account for interface shear strength along a geocomposite drain. Geotextiles must be more permeable than fill material to prevent build-up during precipitation. Special emphasis on the design and construction of subsurface drainage features is recommended for structures where drainage is critical for maintaining slope stability. Redundancy in the drainage system is also recommended for these cases. Surface water runoff should be collected above the reinforced [...] overall slope stability were 40 ft for the bottom three geogrid layers and 30 ft at the top of the slope. The slope face was constructed using prefabricated welded wire forms bents to the specified slope batter of 45°. A secondary reinforcement and a seven ounce non-woven geotextile were place in each wire form prior to primary geogrid placement and compacted soil. The secondary reinforcement provided surficial slope stability and a minimum 6 ft top and bottom embedment specified by

it was shown that the use of horizontally placed geosynthetic reinforcement to stabilize surficial soils in slope applications is a commonplace procedure. For steep reinforced slopes, for example, relatively short secondary reinforcement layers are placed between the primary reinforcement to provided stability to the surface soil during and after construction to help with the growth of vegetation.

Page 3 Version 100119 REINFORCED SOIL SLOPES AND EMBANKMENTS For the purposes of this document, a reinforced slope is defined as a compacted fill embankment that incorporates the use of horizontally placed geosynthetic reinforcement to enhance the stability of the soil structure. This broad definition encompasses many and varied applications. In this [...] the slope’s factor of safety. Reinforcement layers intersecting the potential failure surface are assumed to increase the resisting moment or force. The design process must address all possible failure modes that a reinforced (or unreinforced) slope will potentially experience (see figure 2). The design process must address: • Internal stability for the condition where the failure plane crosses the reinforcement, • External stability for the condition where the failure plane is located outside

The primary reinforcement provides overall stability, while the intended purpose of the secondary reinforcement is to reduce raveling and minifailures of the slope face between the primary reinforcement layers. However, in many cases the secondary reinforcement does not effectively reduce the raveling and mini-failures long term. This has resulted in significantly increased maintenance costs on many projects. Until recently, no viable solution for this problem was available. Within the past [...] of slopes. This combination of geosynthetics has the potential to virtually eliminate any significant future maintenance problems due to raveling and mini-failures at the slope face, for properly designed reinforced embankments. Brief case histories of slopes constructed using fiber-reinforced soil, and design examples using high-strength geotextile - fibers composite are discussed. [...] Planar geosynthetics such as high-strength geotextiles and geogrids have been in widespread use as earth slope reinforcement for more than a decade. The use of these materials in slope applications has been highly successful. Common practice has been to provide primary reinforcement in discrete layers throughout the reinforced zone, with shorter, intermittent layers of the planar reinforcement placed between the primary layers at the slope face to act as secondary reinforcement.

Geosynthetic materials, including geotextiles and geogrids, play a versatile role in RSS, enhancing structural support, facilitating drainage, and supporting vegetation growth. These synthetic solutions bridge the gap between soft and hard facing options for reinforced slopes, offering tailored reinforcement that meets specific site requirements. They are particularly valuable in environments subjected to dynamic weather conditions and hydraulic pressures, where traditional materials might fail [...] ### Design principles of reinforced soil slopes
The design of reinforced soil slopes hinges on two critical components: the facing system and the reinforcement strategy. The facing system is integral to erosion protection and structural support, enabling the formation of slopes that surpass natural stable inclinations without compromising stability. Secondary reinforcement, typically comprising geosynthetic materials, aids in compaction and mitigates surficial sloughing at the slope face. [...] Reinforced soil slopes represent a fusion of engineering excellence and environmental consciousness, addressing both structural and ecological challenges in slope management. Through strategic design, the selection of appropriate facing options, and the integration of advanced materials, RSS provide effective solutions for maintaining slope stability and controlling erosion. As engineering practices evolve, the ongoing innovation in materials and design approaches will continue to enhance the
