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 [...] compactor to work close to the slope face for good compaction of the reinforced fill. Sandy soil from a nearby borrow area was used as the reinforced fill, and this was placed in lifts and compacted using a 10 tonne roller to achieve a minimum of 90% of standard Proctor density. A green colored geotextile mesh was used as a wraparound on the slope surface. 151 Case Study #40: Maehongson Slope Restoration Location: Maehongson, Thailand Owner: Chiangmai Bureau of Highways Engineer: Chiangmai [...] same time prevented surface water from running off too quickly. Cost Effectiveness: Compared to the angular retaining wall, which was considered in the preliminary planning, the final solution was 50% cheaper. 164 Case Study #54: Three Failures of a Steep Reinforced Slope Location: Nantou, Taiwan Purpose: Maximize Available Land Geosynthetic Material: Reinforcement: Polyester Geogrid (3200-17800 lb/ft) Facing: Polyester Geogrid Slope Height: 131 ft Slope Length: 1411 ft Slope Angle: 63°

In the bottom half of the reinforced slope layers of Mirafi® PET HS geotextile reinforcement were installed at 0.45 m vertical spacings. Above this, layers of Mirafi® PET HS geotextile reinforcement were installed at 0.9 m vertical spacings. The steep reinforced slope solution enabled construction to be carried out quickly and resulted in a “green” solution versus the originally proposed concrete retaining wall. Client: Gwinnett Convention and Visitors Bureau, Georgia, USA. [...] Sandy soil from a nearby borrow area was used as the reinforced fill, and this was placed in lifts and compacted using a 10 tonne roller to achieve a minimum of 90% of standard Proctor density. A green coloured geotextile mesh was used as a wrap-around (around the soil-filled bags) on the slope surface. This geotextile mesh reinforces the Completed reinforced slope with vegetation being established Installing the gabion toe of the reinforced slope Compacting the reinforced fill Reinforced slope [...] The slope facing consisted of 0.45 m high galvanized steel mesh units aligned to a 3V:1H slope angle. Inside these mesh units a grid geotextile was placed to contain the reinforced fill placed behind the steel mesh. After completion, the face was vegetated with the slope face being covered with grass quickly.

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. [...] Within the past seven years, short geosynthetic fibers ( Geofibers have been successfully used on more than 25 slope projects in the United States. These projects have involved repairs of shallow slope failures, repair of deepseated slope failures, and veneer reinforcement in new slope construction to reduce future maintenance costs. These fibers also have tremendous potential for use as veneer and secondary reinforcement in geotextile - fibers composite reinforcement of slopes. This [...] Home

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. [...] 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
