CONCLUSIONS
Juárez Badillo (2005) maintain that the magnitude and evolution
of the settlement of embankments in practice are described by
the general equation (4). The total settlement S
T
may be
obtained from the EOS (end of secondary) compressibility
curve (Juárez Badillo 1988) of the subsoil using the
compressibility coefficient γ in equation (8) for its
determination. The fluidity coefficient δ and the characteristic
time t* require, at present, experimental test fills to study the
factors that influence their values in a certain place. A very
important point is to have a clear distinction between the two
compressibility curves: the EOP (end of primary) and the EOS
(end of secondary). Quasi OCR of 1 to 1.8 in practice
correspond to a true OCR=1 in many cases. The difference has
been illustrated in this paper by the application of Eq. (4) to the
important case of the Kansai International Airport.
The important conclusion for this paper is precisely the fact that
the settlement rate in the last eight years tend towards the
theoretical curve obtained by the Principle of Natural
Proportionality.
