critical state soil mechanics

Critical State Soil Mechanics is a framework used to understand how soils behave under different conditions of stress and deformation. It explains how soils continue to deform and change strength until reaching a "critical state," where they settle at constant volume and strength despite ongoing stress. This concept helps engineers predict soil stability and design foundations by analyzing how soils respond to loads over time. Essentially, it provides a scientific way to anticipate soil behavior during construction and loading, ensuring safety and durability in geotechnical projects.
