Study on Landfill Slope Stability under the Condition of Rainfall
Based on fluid-solid interaction mechanics theory, a coupled mathematical model for describing the slope stability of landfill under the condition of rainfall was developed. The model is used to evaluate the safety of the slope. The model simulates the effect of the slope gradient ratio and the slope angle on the slope stability under the different conditions of rainfall in the return periods. Results show that slope safety factor in the different rainfall conditions decreases with the increase in rainfall of time. When the slope gradient ratio is 1:2.5 and 1:3.0, slope safety factor decreased slowly in the value of the allowed range. Therefore, the theoretical basis is more credible provided for designing and appraising stability of the landfill, based on the assessment of the effect of slope gradient ratio on the slope stability in the different rainfall conditions of the return periods.
