Abstract

Sanitary landfills have advantages in low investment, large treatment volume, and strong adaptability, which is now the main treatment for municipal solid waste in China. However, flow slides, which present serious threat to the safety of lives and properties, are prone to occur in Chinese landfill due to leachate mound. To achieve maximum reduction in disaster loss induced by flow slides at landfills, we preliminarily explored simulation-based hazard management of a constructed landfill for flow slides scenario. A well-calibrated in-house numerical method of smoothed particle hydrodynamics was employed to conduct hazard management of flow slides. The flow slide scenario at the landfill was firstly assessed by selecting velocity and runout of flow slides to quantify the hazard. Then, different control measures, including initiative and passive prevention and control measures, were evaluated based on the achievement of hazard assessment. The proposed frame of simulation-based hazard management of flow slides can be applied to constructed or planned landfills, which can mitigate or even prevent similar disasters.
