Slope stability analysis of a landfill subjected to leachate recirculation and aeration considering bio-hydro coupled processes

Abstract: During the operation of landfills, leachate recirculation and aeration are widely applied to accelerate the waste stabilization process. However, these strategies may induce high pore pressures in waste, thereby affecting the stability of the landfill slope. Therefore, a three-dimensional numerical analysis for landfill slope stability during leachate recirculation and aeration is performed in this study using strength reduction method. The bio-hydro coupled processes of waste are simulated by a previously rep… Show more

“…The area transacted by profile 6, besides showing an extensive layer with low resistivities (<10.445 Ω.m), has been considered in similar studies as a saturated zone and groundwater under leachate influence [45,59]. In the north of the dump, two localized points of resistive anomalies were identified as "hot spots" [60,61] resulting from vertical migration and localized accumulation of contaminants Feng et al [62], and may be associated with the confined aquifer system, described in this zone as quite vulnerable to contamination given its proximity to the surface and sandy characteristics of the vadose zone [26].…”

“…Soils have specific properties, indicative of contamination (Khomiakov 2020;Zamulina et al 2021). These properties represent a major role in the fixation, adsorption, and absorption of heavy metals (Feng et al 2021;Yap et al 2022). Factors such as pH, organic matter (OM), moisture, color, texture, and electrical conductivity (EC), are pointed as relevant to assess contamination processes (Fatoba et al 2021;Hussein et al 2021).…”
