Cross Validation of Computational Model Predictions against the Analytical Solutions for the Response of a Heat Exchanger Pile Subjected to Thermal Loading
A cross validation between the predictions of a response of an energy pile obtained by the computational and analytical models is presented. The computational model performed a coupled thermal hydro-mechanical finite element analysis. The pile is surrounded by a single soil underlain by bedrock. Two scenarios of the history of temperature change relative to the temperature of a surrounding soil were applied to the pile. During the first loading scenario the pile remained in the net heated state while the second load scenario induced the net cooling state. The net heating induced an upward axial displacement, tensile strain, and compressive stress while the net cooling induced a downward vertical pile displacement, compressive strain, and tensile stress. While the assumptions used by the two models differ to some extent their predictions of the pile vertical displacement along with strain and stress over the range of temperatures show a very good agreement.
