Abstract：
 The invention is a large-scale multifunctional material three-shaft static and dynamic tester, for providing a three-shaft static and dynamic tester for testing various materials, able to be adaptive to measure the mechanical performance of earth and stone and concrete materials, and also able to make separate seepage as well as seepage and stress coupling, and its characteristic: its main machine part includes side oil water exchange vat and serial water cylinder, side hydraulic cylinder driving the side oil water exchange cylinder,, seepage water cylinder, arranged at the bottom of the main machine and connected with the sample held in a three-shaft pressure room, and seepage hydraulic cylinder driving the seepage water cylinder, the serial water cylinder, is connected with the water path of the three-shaft pressure room through the side oil water exchange cylinder, the upper part of a piston rod driven by an axial vibration exciter is connected with the serial water cylinder and the lower part of the piston rod is connected with the sample held in the three-shaft pressure room. The tester of the invention has high rigidity, high measuring and control accuracy, multiple functions, and is extremely adaptive to material scientific research and engineering detection.
