ABSTRACT
Soil-Water Characteristic Curve (SWCC) is important for understanding different behavior of unsaturated soil such as strength, permeation, compressibility etc. Each soil has got a peculiar SWCC that may get influenced by different factors. This paper describes a few experimental results for obtaining continuous drying SWCC for a cohesionless soil with different initial water contents and dry densities using a tensiometer and a volumetric water content sensor. The main objective of this paper is to investigate the effect of the above mentioned parameters on SWCC of cohesionless soil. The initial specimen density was controlled by changing compaction energy and water content. The details of the methodology adopted are discussed in this paper. The test results indicates that the SWCC obtained in terms of volumetric water content is more sensitive to the changes in initial water content than the initial dry density.
