HIGH-SPEED AND LONG RANGE FLOW ANALYSIS MODEL OF WASTE BODY AFTER SANITARY MSW LANDFILLS SLOPE UNSTABILITY
If the leachate level is excessively high within sanitary MSW Landfills, its failure shows high-speed and long range flow with liquid phase (leachate) carrying about solid phase(waste body) after landfills slope unstability, which likes mud-rock flow. Based on structure two-phase flow theory, and taking consider of the initial conditions, the boundary conditions and the storage condition of waste body flow, the mathematical model of waste masss flow has been established. The discretization model can be established by finite calculus of differences. The high-speed and long range flow of waste mass after landfills slope unstability with high leachate level can be simulated by this model, and the flow distance and the area affected by failed waste mass can be predicted based on simulated results.
