Thermo-pile software

Laboratoire de mécanique des sols (LMS)

Thermo-Pile Software

Thermo-Pile, is based on a discretization of the pile in a number of segments. It enables to consider various soil layers, as well as the variation of the soil properties and temperature with depth. An iterative procedure (finite difference scheme) allows quantifying the thermal strains and the associated additional efforts when the pile is subjected to both axial mechanical loading and temperature changes.The procedure has been coded in the Java language. The numerical tool is based on the form of an interactive application with pop-up menus and windows for input data. Temperatures resulting from energy design of the heat-exchanger pile system can be used as input parameters of the present numerical tool. The calculation can be directly run and the results (stored in text files) can be visualized on various graphs plotted automatically, showing in particular the mobilized friction (with respect to the soil bearing capacity), the stresses in the pile (with respect to the pile structural resistance) and the deformations, for a given thermal loading.


Thermo-Pile 1.02

Thermo-Pile 1.02 is available in two different editions:

  • Enterprise Edition: this edition allows the use of Thermo-Pile as expertise or design tool. Enterprise Edition gives right to the commercial use of the software for private or public institutions.
  • Academic Edition: this edition is for academic institutions for a non-commercial use or education purpose only. When used in published studies, Thermo-Pile should be referred to as the producer of the corresponding results.

Don’t hesitate to have a look at the Thermo-Pile brochure for further pieces of information.
