摘　　要：介绍一种新型双向激振电液伺服式动态三轴试验机,内置潜水式高精度围压补偿轴向负荷传感器,减少了摩擦力的影响,提高了测量精度。全数字电液伺服控制系统很好地解决了土工试验过程中控制方式切换冲击问题,配备的体变测量装置和电气修正补偿系统可以进行非饱和土试验。通过对不同直径试样试验中的电气自动补偿,解决了土工试验中各因素之间复杂的相互影响问题。The article describes a new type of bi-directional excitation electric dynamic servo-control triaxial test. machine, builtin diving- pressure compensation axial load sensor which reduced effect of friction and improved measurement accuracy. All digital electro-hydraulic servo control system may solve a problem of control response in soil test process. Equipment and electrical compensation system for volume deformation measuring were fitted for test of unsaturated soil. Programme of electric auto-compensation for specimen of different diameters can be resolve problem of complex interaction of elements in the soil triaxial test.
