Critical state modeling of lower-bound threshold stress for clay subgrade

Critical state modeling of lower-bound threshold stress for clay subgrade

Railway track foundation with fine-grained subgrade, under loading of cyclic nature, can build up excess pore pressure and results in progressive shear failure at a stress level less than its static undrained strength. It is widely accepted a threshold stress level exists, where loading above such l...
