| dc.description.abstract | To improve accessibility and capacity for traffic in the industrial sector, which is
helpful in raising productivity, the Cibitung-Cilincing toll road was developed in Bekasi
City. This last project's analysis aims to compare the slope's safety factor before and after
it has been strengthened using geotextiles.
The method used on the existing slope is by using the plaxis 8.6 program and to
find the safety value of the slope with the Slice Method (Fellenius). On the slopes
reinforced with geotextiles, the analysis was carried out using the plaxis 8.6 program and
groundwater table variations were also taken into account in the design with variation of
6 meter, 4 meter, 3 meter, and 0 meter.
The safe value for the 12.5m embankment was obtained when the original soil
was 1.1138 for traffic structure load and 1.1131 for traffic and earthquake load.
Geotextiles were then used to strengthen the 12.5m embankment. The reinforced 12.5 m
embankment's analysis with reinforcement produced a higher safety number than was
necessary of 1.3 that are 1.3983 for traffic structure load and 1.3322 for traffic and
earthquake load.. For a groundwater level of 6 meters, the slope safety figure for selfloading
is
1.3297,
with
vehicle
loads
and
earthquakes
being
1.3280.
For
a
groundwater
level
of
4
meters,
the
slope
safety
figure
with
self-load
is
1.3263,
and
with
vehicle
loads
and
earthquakes
is
1.3252.
At
a
groundwater
level
of
3
meters,
the
slope
safety
figure
with
self-loading
is
1.3210,
and
with
vehicle
loads
and
earthquake
loads
is
1.3033.
At
a
groundwater
level
of
0
meters,
the
slope
safety
figure
with
self-loading
is
1.0970,
and
with
vehicle
loads
and
earthquake
loads
is
1.0891.
Thus,
all
slope
safety
values
meet
the
requirements
>
1.3
except
the
0
meter
groundwater
level
that
below
1.3
but
above
1.0
ehich
means
have
a
doubtful
stability
condition.
Based
on
the
analysis
above,
slopes
with
geotextile
reinforcement
are
able
to
withstand
landslides
up
to
a
groundwater
level
of
3
meters
from
the
surface
of
the
slope. | en_US |
