Título del libro: Geotechnical Engineering In The Xxi Century: Lessons Learned And Future Challenges Título del capítulo: New Analytical Solution for Embankments, Considering a Rigid Lower Boundary
This paper presents a new analytical solution SATFI (Analytical solution
for embankment with a rigid lower boundary, by acronym in Spanish), to
calculate vertical displacements induced by an embankment. The results
obtained include the effect of a rigid lower boundary where
displacements are restricted. SATFI is based on the analytical solution
by Manica (2012), which is an extension of Carothers (1920) solution. In
order to perform the calculations automatically, an algorithm named
TEFRI was developed in MATLAB (embankment with a rigid lower boundary,
by acronym in Spanish). With the help of this logarithm, it is possible
generate contour maps and graphs of displacements on vertical and
horizontal axes. In this research work TEFRI is used for solving the
case of an embankment built on a deposit with characteristics typical of
the subsoil of the Valley of Mexico City. The analyses are carried out
considering different depths of the firm stratum, where the
displacements are considered as negligible, and drained and undrained
conditions of the soil. The results obtained are compared with the
results of the numerical modeling corresponding to the mentioned cases.
A good agreement between the results obtained between the analytical and
numerical models.
