Abstract:
The prediction of the settlement of municipal solid waste(MSW)is important to guide the design, build and use of landfill. Based on the feature that settlement deformation under the linear load condition present the “S” form of MSW, the Usher model was used to predict the change law with time of settlement by the variable separation method with the initial condition. The result show that the Logistic model and Gompertz model is the special examples of Usher model. The repetition duality regression method was adopted to solve parameters and to calculate the settlement of a MSW. The error square of Usher model, Logistic model and Gompertz model was 108.19, 162.21 and 952.41 respectively. The results indicate that the Usher model in predicting the settlement is reasonable and have a higher forecast accuracy, it can be adopted in engineering practice. 1 tab, 1 fig, 10 refs.
