Resumen:

In this article a procedure is presented in order to calculate the settlement of a foundation in sand. It uses a nonlinear differential constitutive equation that is integrated in the domain of the confinement pressure over the soil; we obtain then a constitutive equation that takes into account the variation of confinement pressure due to the presence of an engineering construction. This procedure is in advance of other methods which not consider the increase of compression over the soil, especially when the increments of stresses are high. Moreover, in the constitutive equation we use very few mechanical properties which do no change with the variation of confinement pressure.
