AI Technical Summary

Technical Problem

The prior art lacks indoor testing equipment for energy pile bearing performance, especially in frozen soil areas, which makes it difficult to study pile-soil interactions and changes in pile bearing performance.

Method used

An energy pile bearing performance test device including a reaction force system, a loading system, an energy control system, a pile and soil system and a measurement and acquisition system is designed. The device simulates pile-soil interactions through model boxes and model piles, and uses energy U-shaped tubes and energy control microtubes to control energy changes in piles and soil.

Benefits of technology

The experimental research on the bearing performance of energy piles and pile-soil interactions indoors is realized, which can intuitively observe the interaction process of piles and soil, and simulate changes in piles and load conditions.

Abstract

The present invention discloses an energy pile bearing performance test device, including a reaction force system, a loading system, an energy control system, a pile-soil system and a measurement and collection system; the collection system can intuitively observe the energy change process of the energy pile and the soil around the pile, as well as the interaction and deformation characteristics of the pile-soil, and can carry out the bearing performance, deformation characteristics, physical and mechanical state changes and deformation characteristics of the soil around the pile during the energy change process of the energy pile and the soil. Indoor tests for different soil bodies and different drainage 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 / conventional piles and energy soil (frozen soil or geothermal soil or soil layers with different temperatures in deep foundations) under combined loads, single loads, cyclic loads and combined cyclic loads can be carried out.
