Abstract

Settlement prediction of solid waste landfills is important for their post-closure operation. Estimation of settlement of refuse is complex because of the mechanism of settlement and heterogeneity of the refuse. Several methods are available to predict the settlement of solid waste landfills. Based on the analysis of published measured data of four landfills, a unique relationship was recently developed between reference compressibility and rate of compression to predict refuse settlement using Power Creep Law. A step-by-step procedure is proposed to predict refuse settlement by using the Power Creep Law at a site for which the data from laboratory or field tests are not available. Settlement-time relationships predicted using the proposed procedure are compared with actual recorded data from landfills. Predictions show good agreement with the measured settlements.

Procedure to Predict Settlement of Solid Waste Landfills Using Power Creep Law

St. Louis, Missouri

Settlement prediction of solid waste landfills is important for their post-closure operation. Estimation of settlement of refuse is complex because of the mechanism of settlement and heterogeneity of the refuse. Several methods are available to predict the settlement of solid waste landfills. Based on the analysis of published measured data of four landfills, a unique relationship was recently developed between reference compressibility and rate of compression to predict refuse settlement using Power Creep Law. A step-by-step procedure is proposed to predict refuse settlement by using the Power Creep Law at a site for which the data from laboratory or field tests are not available. Settlement-time relationships predicted using the proposed procedure are compared with actual recorded data from landfills. Predictions show good agreement with the measured settlements.
