I-D COLUMN STUDIES FOR DISSIMILARITY OF GEOTECLNICAL CHARACERISTIS DUE TO LEACHATE OF MUNICIPAL SOLID WASTE ON COMMERCIAL AND NATURAL SOILS

Influence of an MSW leachate on the geotechnical Characteristics (index properties and unconfined compressive strength) due to artificial contamination on five soils (two commercial soils and three natural soils) were investigated by soil-column studies by using fed-batch method. It is inferred that the leachate has played a unique role in influencing the index properties, especially, the shrinkage limit of soils. The strength of soils found to reduce by about 20 %, within the period of contamination.
