Abstract
The present disclosure discloses a device for centrifuge testing of a driven pile in different installation and pull-out modes, including a supporting system, a pile driving system, a pile-soil system and a measurement and acquisition system. The present disclosure further provides a method for operating the device for centrifuge testing of a driven pile in different installation and pull-out modes. The present disclosure can perform geotechnical centrifuge testing of a driven pile through penetration in different installation modes and pull-out in different pull-out modes, and provide the effective test device and method for study of a pile-soil mutual dynamic response during a whole process of penetration and a process of pull-out of the driven pile. Moreover, pile-soil deformation characteristics and the like during the processes of penetration and pull-out can be visually observed through a high-speed camera or a digital camera, and the pull-out and penetration can be tested separately.
