| Sumario: | ABSTRACT In this paper, a simplified analytical model for the design of friction piles foundations in an environment that is prone to regional subsidence is presented. The model is based on Mindlin's equations and was originally proposed by Reséndiz and Auvinet. Some important modifications of the original version based on the results obtained from numeric analyses have been introduced. In this new version, negative skin friction is evaluated taking into consideration initial and future effective stresses conditions and not only the limit shear strength of the soil in contact with the pile system. The model was validated with results previously obtained by the authors using the Axisymmetric Finite Element Method. In spite of the differences observed during such validation, it was possible to conclude that a reasonably good match exists between both models. |
