英文摘要: Abstract(#br)In bioreactor landfills, leachate recirculation system can significantly promote moisture distribution, thereby enhancing the biodegradation of municipal solid waste (MSW). However, it increases pore pressure inside landfills, which can greatly affect slope stability. In this study, a three-dimensional numerical model is established to study the landfill slope stability under leachate recirculation through Vertical Wells (VWs). A leachate flow model is adopted to describe the migration of leachate, and the distribution of pore pressure is then used to calculate the Factor of Safety ( FS ) using strength reduction method. A large number of simulations are conducted using the proposed model to investigate the influences of injection pressure, hydraulic and mechanical...
