摘　　要：针对北京工业大学新引进的全自动静一动三轴剪切仪的设备功能进行了系统分析,该设备既能完成普通的静动三轴剪切试验,还能完成径向-轴向耦合剪切试验,可实现各种特殊复杂应力路径及分级加卸载静态剪切试验,此试验剪切过程均可通过计算机自动控制.并对利用全自动静-动三轴剪切仪实测得到的试验结果进行了分析.试验结果表明,该仪器测试精度较高,在土工试验中具有较广泛的应用性,为研究复杂应力条件下的实际土体强度与变形特性的研究提供了试验技术条件.A Fully Automatic Static-dynamic Triaxial Shear Apparatus was purchased by Beijing University of Technology recently. It has many good functions that many tests can be clone using the apparatus, including ordinary static and dynamic triaxial shear test, mixed （radial-axial） coupling shear test, and so on. It also can carry out diversified special complex stress paths and graduated loading or unloading static shear test. All the shear process can be controlled by computer automatically. In this paper, the equipment function of the Fully Automatic Static-dynamic Triaxial Shear Apparatus is systematically introduced. Then, some tests are carried out, and the test results indicate that the apparatus has good precision and wide applicability. So, the soil＇s mechanics capability under complex stress conditions can be clone using this apparatus.
