The development of an optimal energy pile system involves complex analyzes. It comprises the selection of objective functions, the detection of decision variables and system design constraints, then the best optimization method.
From the structural view, the possibility of failure of an energy pile system due to excessive expansion or extraction resulting from thermal exchange needs to be checked. In this section, the 4E-G criteria relating to the design of energy piles, both thermally and mechanically, are reviewed (Table 7).
The heat flow should also be addressed to consider the actual thermal behavior of energy piles. The thermally-induced changes of stresses and strains in energy piles depend strongly on the pile fixity and can reach critical values if the restraint conditions are not correctly defined.
The increase in cycle number reduces the irreversible settlement. Higher axial force at the end of heating compared to cooling. The temperature change and the restraint condition affect the expansion and contraction of the energy piles. The deformation of energy piles is elastic.
The thermal process goes in an energy pile, as in a borehole heat exchanger, in different stages: heat transfer through the ground, conduction through pile concrete and heat exchanger pipes, and convection in the fluid and at the interface with the inner surface of the pipes (Fig. 2).
