Thanks for the reply. Indeed the freezing depth is among the first that need to be quantified, I think a coupled THM FE model would be necessary to find the long-term 0 oC isothermal. Since the piles are large in comparison to their mesh a large model is needed (cant assume axis symmetry and...
I'm quoting a high-rise cold storage (2.800m2 X 30m height) founded on a friction-pile raft foundation, where the raft is also the final floor. Raft thickness is 1,00m due to the racking's anchorage demands. The freezer temperature is -22 Celsius (-8 F) and the water table is about 2m below...
