Analytical modelling of capacity and deformation of energy pile groups

Abstract

Abstract This chapter focuses on the analysis of the capacity and deformation of energy pile groups subjected to axial mechanical loads and thermal loads. Analytical and semianalytical approaches to model both the failure of energy piles induced by axial mechanical loads and the deformation of such foundations caused by axial mechanical loads and thermal loads are proposed. The predictions resulting from the application of the discussed approaches are compared with more rigorous numerical results as well as with full scale in situ test results, and the capabilities of such methods are discussed. The developments presented in this chapter complement the analytical solutions discussed in Chapter 10, Analytical modelling of capacity and deformation of single energy piles, for single energy piles and may be employed to predict the actual response of such foundations described in Chapters 6, Thermomechanical behaviour of single energy piles and Chapter 7, Thermomechanical behaviour of energy pile groups.
