for designing geotextile-reinforced slopes and an example case was investigated based on the suggested approach. Reinforced earth slopes consisting of fly ash-based fill materials have many benefits, including low unit weight, resulting in lower net pressure imparted on the foundation soil and reuse of waste material generated from coal-based thermal power plants. A. Problem 1. Reinforced Slope Design A 1H:1V geotextile reinforced road embankment made of fly ash mixed soil on the existing [...] prescribed by . These charts were developed by performing wedge analysis of geotextile-reinforced slopes made of cohesionless soil. The results were presented in graphical form by combining the results of wedge analysis. The graphs present the values of a few relevant parameters, such as reinforcement force coefficient K and reinforcement length ratios (LB/H or LT/H) against different slope angles. The reinforcement force coefficient K determined from these charts can be used to determine [...] stability analysis of unreinforced and reinforced soil slopes using non-circular slip surface," Acta Geotechnica, vol. 14, no. 3, pp. 907–919, Jun. 2019, 10.1007/s11440-018-0678-x.

are typical of sandy soils often encountered in landscape projects. Six cases in all were analyzed and a dimensionless stability number (N) defined in Eq.

Proceedings of the 11th International Conference on Geosynthetics 16-21 September 2018, Seoul, Korea N=c’/γHtan ϕ’ (1) where c’ and ϕ’ are the effective shear strength parameters [...] this analysis that reinforcing the slope will improve F by 47% (almost double) from unstable state (F<1) to a stable condition (F = 1.25). 5. CONCLUSIONS A parametric study has been conducted to determine the influence of soil strength parameters on the factor of safety of low-height (3 m) unreinforced and reinforced slopes with varying angles from 40° to 60°. The study was conducted using the limit equilibrium method, available in the commercial software, Slope/W. Based on the results and [...] 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

Appendices H and I provide a summary of published case study information and case study survey results. PURPOSE Geosynthetics were employed for these projects to improve soil conditions by providing tensile resistance and stability. As per Figure 30, reinforced slopes were utilized in most of the case studies as a structure for supporting roadways, bridge abutments, buildings, railways, and [...] Case Studies #54 and #60 provide detail regarding slope failures that have occurred in Taiwan and the United States, respectively. Observations led to the conclusion that the failures were closely related to poor embankment fill and drainage systems. Moisture migration produced adverse influences on the stability of the reinforced slope systems. COST EFFECTIVENESS In the case studies, constructing GRSS was determined to be the most practical and cost effective option when compared to [...] it is possible to build reinforced slopes in many different environments provided that space constraints and site conditions allow proper access. Slope geometry after construction was available for most of the case studies, and Figure 32 illustrates the height and angle of the GRSS. The height of the slopes ranged from 8 ft to 242 ft.

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 [...] 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 [...] ## Cited by (5)

Abstract/Additional Information
Paper on file with ASDSO. [...] 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. The primary
