摘　　要：针对北京工业大学新引进的竖向-扭转双向耦合剪切仪的功能进行了分析,该设备可完成多种固结条件及加载方式的静动力试验,适用范围广泛.试验结果表明:竖向-扭转双向耦合剪切仪能较好地分析土体在复杂应力条件下的变形与强度特性,试验结果合理可靠,具有较高的精确度.Vertical -Torsional Coupling Shear Apparatus was purchased by Beijing University of Technology recently. This apparatus can reproduce complex stress conditions and stress paths, and also can be used to perform static and dynamic soil experimental tests of sands or clays under complex consolidation condition. The test results indicate that the soil＇ s characteristics of deformation and strength under complex stress conditions can be done by using this apparatus. It has good precision and its results are reasonable and reliable.
