(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. [...] by Zonberg et al. (1998) and Tiwari and Samadhiya (2016) for reinforced slopes, a parametric study was carried out on the 40°, 50°, and 60° slopes (unreinforced and reinforced) as presented in Figure 2 (a-d) by varying the slope soil strength parameters (c’ from 0 to 5 kPa and ϕ’ from 30° to 50°), while keeping the slope height, geosynthetic layout and soil unit weight constant, to determine their effect on the factor of safety, F. The range of c’ and ϕ’ adopted in the study are typical of [...] 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.

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 [...] 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 [...] 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

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. Inextensible reinforcements consist of bars or bar mats (metallic grids) and shall meet the requirements in STS SC-M-713 (latest version) for Geotechnical Design Manual APPENDIX D January 2022 D-25 Mechanically Stabilized Earth (MSE) Walls for the inextensible material properties. These [...] 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 [...] reinforced slope with a computer program. Layout includes number, length, design strength, and vertical distribution of the geosynthetic reinforcement. The charts presented in Figure D-8 provide a method for generating a preliminary layout. Note that these charts were developed with the specific assumptions noted in this figure. Analyze the reinforced soil slope with the trial geosynthetic reinforcement layouts. The most economical reinforcement layout must provide the maximum stability

A reinforced soil slope is defined as a compacted fill embankment that incorporates geosynthetic reinforcement to increase the soil shear to enhance the stability of the embankment when site conditions require an embankment with a steeper angle of repose (how steep soil can naturally be piled relative to a horizontal plane) or if the embankment is intended to carry a load considered unstable with the existing subgrade. [...] When building a reinforced slope, we will primarily depend on a secondary reinforcement with a light to moderate geosynthetic fabric or grid in tight vertical spacing with relatively short embedment lengths (how far horizontally into the slope these extend). These layers will provide superficial stability to protect the embankment from shallow plane failure at the surface, while also giving compaction equipment a good platform in which to compact soil lifts all the way to the face of the slope. [...] ### Step 2 – Reinforcement Placement
Place reinforcement as determined by construction drawings to match embedment, elevation, and orientation as determined by the design engineer. Ensure geosynthetic reinforcement is free of wrinkles and folds and is pulled taught by using soil staples or pins. Splicing in the direction parallel to the face of the slope is prohibited.
