Energy pile bearing performance test device and operation method thereof

The invention discloses an energy pile bearing performance test device. The device comprises a counter-force system, a loading system, an energy control system, a pile-soil system and a measurement and collection system. According to the collection system, the energy changing process of an energy pile and soil around the pile as well as the interaction and deformation characteristics of the pile and the soil can be visually observed, and tests on the bearing performance and the deformation characteristics of the pile, the physical and mechanical state changes and the deformation characteristics of the soil around the pile and the like in the energy changing process of the energy pile and soil body can be performed. Indoor tests for different soil bodies and different drainage working conditions can be carried out, and geotechnical centrifuge tests can also be carried out. Conventional indoor tests and geotechnical centrifuge tests such as pile-soil interaction between energy piles or between conventional pile
