Analyzing piles subjected to lateral loads significantly depends on soil resistance at any point along the pile as a function of pile deflection, known as p-y curve. On the other hand, the deformation characteristics of soil defined as “the soil strain at 50% of maximum deviatoric stress (ε50)” has considerable effect on the generated p-y curve. In this research, several models are proposed to ...

This study investigates the thermo-mechanical behavior of energy piles equipped with a spiral pipe configuration. The analysis is based on results full-scale pile as well three-dimensional finite element analyses. two five U-shaped pipes connected in series and parallel, characterized by same total length piping network, also analyzed numerically for comparison purposes. this work highlight tha...

Abstract The traditional steam maintenance process of concrete prestressed pipe piles adopts maintenance, and the energy utilization rate is not high due to inaccurate temperature automatic control system in steaming pool serious loss during process. In order effectively ensure strength durability pre-products, shorten production cycle at same time, realize automation pond system, new by manual...

We show that the one-dimensional Oslo rice-pile model is a special case of the abelian distributed processors model. The exact steady state of the model is determined. We show that the time evolution operator W for the system satisfies the equation Wn+1 = Wn where n = L(L + 1)/2 for a pile with L sites. This is used to prove that W has only one eigenvalue 1 corresponding to the steady state, an...
