Study on measuring methodologies and critical parameters influencing soil suction water content relationship

Abstract

The knowledge of unsaturated soil behaviour is indispensable for many of the field situations such as compacted pavements swelling clays slopes embankments shallow waste disposal facilities etc one of the important attributes of unsaturated soil is the negative pore water pressure or soil suction existing in it The study of unsaturated soil behaviour is dependent on the basic relationship between soil suction and water content either gravimetric or volumetric or soil saturation Such a
