To saturate a soil specimen in Dynamic Triaxial tests, we follow the same procedure as in static Triaxial tests, i.e. by gradually elevating the Back pressure so that pore air is dissolved into pore water. Saturation checks are performed by elevating the confining pressure to the specimen and keeping the drainage valve closed. global industrial dry erase board
