LARGE-SIZE MULTIFUNCTIONAL INTERFACE POWER SHEAR TESTER AND TEST METHOD

摘要

The present invention relates to the technical field of geotechnical engineering, and provides a large-size multifunctional interface power shear tester and test method. The tester comprises an oil source system, a control system, and a shear system; the shear system is a main body device for carrying out a shear test, and comprises: a mainframe, vertical and horizontal actuators, upper and lower shear boxes, and a test auxiliary tool, the vertical and horizontal actuators are respectively connected to the upper and lower shear boxes, and the test auxiliary tool comprises tine plates, a side limit frame, a soil grabbing device sensor and the like; the oil source system is a power device and is used for providing power to the two actuators; the control system is a device for collecting control and sensor signals of the tester, and is used for accurately controlling and monitoring an operation state of the tester. According to the present invention, by accurately controlling motion states of two actuators, multiple test functions such as different interface types and test materials, and different power shear modes can be achieved, and the deficiency of current interface power shear test technical means is overcome.
