Complex working condition multi-type energy pile model test device and method

The invention discloses a complex working condition multi-type energy pile model test device and method, and mainly relates to the field of simulation test devices used in the civil engineering field. Comprising a model tank, a model pile, a measuring system, a water circulation heat exchange system and a loading system, the model tank is an outer tank which is formed by enclosing special materials and is in various shapes, one side of the model tank is provided with a water inlet and two water outlets, and a double-layer transparent plastic film with water in the middle is tightly attached to the inner wall of the model tank. The datum beam stretches across the two sides of the model groove and is connected with a longitudinal counter-force frame welded to the outer wall of the model groove. The model pile selects a proper pile type according to different construction conditions, and the measuring system comprises a static strain testing system, a concrete strain gauge, a resistance type miniature soil press
