In order to study the influence of soil mechanical parameters and leachate level on slope stability coefficient under load, the soil mechanical parameters and related data of a landfill site in Guangdong were obtained through field exploration sampling and laboratory test. The finite element model was established by coupling each module of Geostudio software, parameters sensitive to the stability of garbage dam body such as boundary load and leachate level were applied, and parameter sensitivity analysis was carried out. At the same time, the safety coefficient of garbage dam was solved by simulating the force between bars and establishing the mechanical balance equation, so as to master the sensitivity of each parameter to the safety and stability of the dam body. The study shows that the sensitivity of leachate water level change to safety factor is relatively large. The stability analysis of this simulation can be used as a reference for the stability analysis of earth-rock dams in landfills in the future. [ABSTRACT FROM AUTHOR]
