Dynamic triaxial test system is a basic equipment for researching soil dynamic properties. Model DSZ-1 electromagnetic dynamic triaxial test system is improved and carried out by the authors. Rolling diaphragm is used as pneumatic bearing and a linear motion bearing is used under triaxial cell. Electromagnetic exciter is made of eight pieces and electromagnetic power is adjustable. This system and resonant column test system use one set of computer control system and static pressure panel. As a result of property test, the system is convenient, steady and accurate for soil dynamic research.
