Título del libro: Geotechnical Engineering In The Xxi Century: Lessons Learned And Future Challenges Título del capítulo: Calculation of Settlement in Sands Using a Non-Linear Constitutive Equation
Deformation of sand; constitutive equation; footing settlement
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.
