Centrifugal device and method for simulating entire process of sequential installation of group piles and negative skin friction

Abstract

The invention relates to the technical field of pile foundations in geotechnical engineering, and in particular to a centrifugal device and method for simulating the entire process of sequential installation of group piles and negative skin friction. The device includes a base plate for installation on a centrifuge, where the top surface of the base plate is fixedly connected with a model box for placing a soil layer; a monitoring component is arranged in the model box; a drainage component is arranged outside the model box; one end of the model box far away from the base plate is detachably connected with a top plate; the top plate is provided with a through groove communicated with the model box; a plurality of pressure components are arranged in the through groove; the pressure components are respectively used for pile driving and applying pressure to the soil layer.
