Unloading Mechanical Behaviors of Clay Considering Initial Principal Stress Direction Effect: Experimental Study and Modified Constitutive Model

Excavation-induced unloading can alter soil response through both stress-path effects and material orientation. This study investigates remolded clay from Jinan using conventional consolidated undrained (CCU) and lateral unloading undrained (LUU) triaxial tests at orientation angles α = 0°, 30°, 45°, 60°, and 90° and e...
