Factors Affecting Stability and Slope Failure of Landfill Sites: A Review

Abstract

Landfill is still the most cost-effective method of solid waste disposal. Every kind of pretreatment and incineration process is applied to the wastes, as a result, non-processable wastes are formed such as ash, non-recyclable wastes, etc. Therefore, the landfill method is still considered to be inevitable. It is essential to prevent slope failure during the entire landfill process such as site construction, waste acceptance, laying-compaction, intermediate cover and final cover. For this, it is important that the planning of the sanitary landfill facility is made by considering the engineering criteria of the project and then the operation. In some landfill facilities, slope failure is experienced at various scales due to mistakes made during these stages. In this study, taking into account the slope failure in the past, cause-effect relationships and mistakes will be analyzed, and determinations about solution alternatives will be made about solution alternatives.
