Unsaturated Soil Mechanics in Engineering Practice Delwyn G. Fredlund1 Abstract: Unsaturated soil mechanics has rapidly become a part of geotechnical engineering practice as a result of solutions that have emerged to a number of key problems or challenges. The solutions have emerged from numerous rese...
1 unsaturated soil behavior are truly commendable and still worthy of study. Subsequent reference to the textbook Theoretical Soil Mechanics during my career, has caused me to ask the question, “Why did unsaturated soil mechanics not emerge simultaneously with saturated soil mechanics?” Pondering ...
unsaturated soil mechanics; soil suction; unsaturated shear strength; soil–water characteristic curves; matric suction1. Introduction The shear strength for an unsaturated soil takes the form of a nonlinear mathematical function with respect to soil suction. Shear strength laboratory testing is both ...
