摘　　要：针对细粒土的复杂应力路径的试验,研制了1台智能化控制的液压伺服多功能三轴试验机,该试验机包括主机、数字化控制系统、动力供给系统三个组成部分;其轴压和围压可实现电液伺服的闭环控制;在静力试验中可实现复杂应力路径的任意控制和加载;在动力试验中可同时施加轴向和侧向的双向振动荷载,且可进行等应变增量比的试验。初步试验表明,该系统结构简单,使用方便,重复性好。Aiming at the fine-grained soil complex stress palh test research, an intelligent mulfifunction triaxial test apparatus is developed which is drived by the hydraulic servo. The testing machine comprises a host, digital control system, hydraulic power supply system. The axial and confining pressure are electro-hydraulic servo closed-loop controlled. It can conduct the conventional triaxial test, dynamics triaxial test, confining pressure shear triaxial test, complex stress path triaxial test, biaxial vibration triaxial test and constant strain increment ratio test. The system is demonstrated for its simplicity and stability during initial experiment.
