Abstract

In this study, geotechnical properties of the subsurface clay stratum obtained from the in-situ tests are compared with those of the relative laboratory tests. The influence of accumulated leachate on the settlement of the landfill and the geotechnical properties of underlying clayed soil are analyzed using the in-situ measured settlement data. The consolidation data is then back-calculated from the settlement data and compared with the laboratory scale consolidation data. It was found that the settlement was retarded by the accumulated leachate and the consolidation properties obtained from the field measurement were 1.5 times higher than the laboratory obtained data, which proves the importance of field measurement of geotechnical data during the operation period.
