摘　　要：土工试验在岩土工程中处于十分重要的地位。河海大学与日本圆井株式会社共同研制了一种新型的多功能静动三轴仪，该设备能进行静应力路径三轴试验、静扭剪、动扭剪、动三轴及垂直振动与周期扭剪双向振动的耦合试验，能模拟动主应力轴旋转、地震液化及液化后大变形等多种复杂的应力条件。文章对其构成和功能以及在液化后大变形研究中的应用进行了介绍。Experiment is very important in geotechnical engineering, a new developed test apparatus, named the static-dynamic dual purpose triaxial compression test apparatus is introduced in the paper. It is designed through cooperation of Hohai University and Marui Co. Ltd. Japan. It can stimulate many complicated stress conditions such as rotation of principal stress axis, sand liquefaction, and earthquake-induced large ground deformation. Its composition and application are introduced.
