After the landfill site is sealed, the uneven settlement is related to the safety of reutilisation of the site, and it is critical to calculate the uneven settlement of the site without error. In this article, the soil parameter of garbage body was changed with biodegradation. Fast Lagrangian Analysis of Continua in three dimensions (FLAC 3D) numerical simulation was applied to the settlement of the landfill site closure. In calculating the settlement of landfill, the soil parameters of landfill with age were obtained by field drilling experiments. The parameters can reflect the characteristics of soil organic matter in different biodegradation stages. Finally, the uneven settlement within 20 years of the closure period was obtained by the numerical simulation taking Jinzhou Nanshan landfill as an example. The results show that the settlement with the age increases gradually, but the rate will be more and more moderate, and the maximum subsidence value in the sealing field after 20 years will be 9.11 m, 15.71% of the maximum elevation. Around the landfill slope position of uneven settlement rate is bigger, and the maximum angle of uneven settlement is up to 45°. But the middle position is small, which is close to 0°.

In order to study the bio-decomposition of bioreactor landfill waste, simulation experiment of different ways of landfill and decomposition stage was conducted. We analyzed decomposition processes of organic matter in different decomposition stages. The landfill can be divided into two types in bioreactor: stratified landfill and non-stratified landfill, each group having four waste decomposition reaction stages. By collecting the reaction gas and leachate in each stage, methane production, pH, moisture content and volatile solids were measured, and the pattern of bio-decomposition was obtained. The results showed that with the gradual deepening of organic matter decomposition in waste, the methane production rate and the pH value of leachate will change greatly. The weight percentage of the biodegradable material gradually decreased and the average moisture content of waste increased from 54.6% to 70.2%. The content of volatile solids in waste decreased from 89% to 51%.

To study the stability of waste body failure in landfill, the landfill was divided into two parts: an active wedge and a passive wedge. A limit equilibrium analysis was used to calculate the safety factor of stability in landfill. The parameters which affected the stability of the landfill were discussed. Sensitivity curves of each parameter were proposed and effect trends of various parameters on safety factor were analyzed. Cohesion c and internal friction angle фs increases linearly with the safety factor. The safety factor decreases with increasing slope angle β and filled height H. The safety factor of after landfill settlement was higher than the safety factor of settlement which did not occur. It increases the overall stability about 16%.
