Construction process
The construction of the wall was complete
in three months. To do this, the
first step was improving the conditions
of the foundation ground. In this phase,
a ground improvement was made by
placing two layers 20 inches (50 cm) of
crushed gravel in two layers reinforced
with triaxial geogrids with the aim of
reducing possible differential seats and
thus improving the bearing capacity of
the foundation soil.
Once this stage was completed, the
6a
20-inch (50 cm) thick draining filter
basket was placed. On top of this layer,
the crushed gravel is protected by placing
a blanket of nonwoven geotextile
and placing reinforced material baskets
vertically spaced every 20 inches (50
cm). The reinforced filling is compacted
with a compaction energy of 95% of the
Modified Proctor with the maximum
density values of 14 KN/m3 and an optimum
humidity of 23.4%. The construction
process is shown in Figure 7 on
page 32.
Conclusions and
recommendations
MSE walls reinforced with geogrids and,
specifically, using the Sierra system, have
good flexibility to be constructed in
various adverse topographic situations.
They also have reduced execution times
that translate into economic savings.
The friction angle is a very important
parameter for the correct interaction
between the geogrid and the soil
particles of the filler material, where
values of friction angle greater than 30°
are recommended to ensure that the
interlocking between geogrids and filler
material occurs.
The comparison between the filler
material used from the 12 + 700 borrow
pit and the Sierra borrow pit produce
a significant effect on the calculation
