摘要：
According to the soil test requirements, a new dynamic & static triaxial apparatus is developed. This apparatus can replace the traditional dynamic triaxial apparatus and static triaxial apparatus to accomplish the testing task perfectly. The implementation of the servo loading is the key of dynamic & static triaxial apparatus. The electro-hydraulic servo loading system is adopted to accomplish the dynamic & static loading of the force and displacement after comparing the advantages and the disadvantages of the hydraulic, pneumatic and electric loadings. In order to resolve the oil pressure fluctuating problem with dynamic loading and low efficiency problem with static loading, a design project of the hydraulic system with the accumulator group and constant pressure pump is proposed. The correctness of the project has been verified by mathematical modeling and simulation.
