It was found that bare slopes deteriorated rapidly under high-intensity rainfall, progressing from splash to severe gully erosion. Vegetation-geotextile system (tall fescue with coconut fiber blankets) considerably delayed runoff, decreased erosion, and improved soil structure and water retention. By contrast, AAB-treated geotextiles displayed superior mechanical stability and erosion resistance due to densified fiber networks and optimized pore structures compared to untreated bare slope. Furthermore, AAB-treated geotextiles delivered the highest erosion resistance, while vegetation-geotextile composites provided significant ecological benefits in terms of soil temperature regulation and organic matter release. As a result, integration of AAB treatment with vegetation-geotextile systems can serve as a long-term slope stabilization solution that simultaneously addresses engineering requirements and environmental objectives under climate change scenarios.</div></div>","PeriodicalId":55096,"journal":{"name":"Geotextiles and Geomembranes","volume":"54 1","pages":"Pages 36-49"},"PeriodicalIF":6.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145158737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The geogrids enhance soil integrity and mitigate PGA amplification factors. They distribute shear stresses to surrounding soil or other geogrids. Low-frequency waves play a predominant role in seismic damage due to their longer propagation distances. Scattering leads to changes in energy distribution as seismic waves propagate through caustic surfaces. The energy attenuation characteristics of high-frequency signal components and the increased contribution of low-frequency components under high PGA conditions are observed. An increase in the difference in variance contribution rate (VCR) indicates inconsistencies in the vibration characteristics of the soil. The sudden changes in Intrinsic mode functions (IMFs) suggest that the energy of seismic waves is amplified and attenuated to varying degrees.

A number of electrical, hydraulic and soil water retention parameters were monitored during the treatment process, and the material response to the EO treatment was evaluated by assessing various geotechnical and physiochemical parameters. The results indicate that, regardless of the voltage gradients, overall, the EO dewatering led to a reduction of at least one-third of the original water content. The EO treatment resulted in a sevenfold, ninefold and twentyfold relative increase in undrained shear strength for the experiments with the lowest, intermediate and highest initial water contents, respectively, indicating an exponential increase as the initial water content of the slurry increases.

The setup consists of a rotating wheel that traverses a sandy path, both with and without geocell reinforcement. Reinforced and non-reinforced results were compared under various scenarios, including wheel velocities and masses. Additionally, the effect of geocell confinement was compared with the effect of apparent cohesion using the theoretical model proposed by Ibagón et al. (2025).
