walls on the lateral sides of the embankments would need to be curved into and
behind the sheet-pile walls to provide a
competent termination of the geosynthetic
walls at the bridge abutments. This would
be relatively easy to accomplish because
the HPTRM can be cut and then pulled
and overlapped to form curves with tight
radii (Miller 2016).
GWFV wall design
Any geosynthetic-reinforced soil mass
must resist the lateral earth pressure of
the retained soil tending to deform and
slide downward and outward due to the
pull of gravity (Rimoldi 2016). It also
must resist the lateral load contribution
from surcharge loading in the backslope

area, such as permanent loads (due to
surface structures) and temporary loads
(due to construction equipment or vehicular traffic).
External wall stability analysis was
conducted for the tallest proposed GWFV
wall section using both allowable stress
design (ASD) and load and resistance factor design (LRFD) methods to evaluated
base sliding, overturning (eccentricity)
and bearing capacity. Calculated results
are summarized in Table 1 for the tallest
wall section with an 11-foot (3.4-m) long
geogrid reinforcement zone.
Internal wall stability analysis focused
on rupture potential for the geogrid primary reinforcement, with 1-foot (0.3m) vertical spacing for the lower lifts,

Any geosyntheticreinforced soil mass
must resist the lateral
earth pressure of the
retained soil tending
to deform and slide
downward and
outward due to
the pull of gravity.

Hey, it's me, Geo The Gopher.
And I say... Stay Dri, Specifi Mirafi ®.
I'm here to tell you about this groundbreaking product from TenCate. It's called
Mirafi® H2Ri and it's the real deal. In fact, it's the only geotextile with enhanced lateral
drainage and the ability to remove water in unsaturated conditions. Plus, its wicking
capabilities are so strong that it can actually move water uphill. Also, it works in any
condition or climate. Impressive, right? We think so too. So put an end to potholes
