| dc.description.abstract | Padang – Pekanbaru Toll Road is a part of the Trans Sumatra Toll Road Network. In
implementations, embankment work is carried out on the road to even out the contours of the land
at the construction site. With the accumulation of soil, new embankment slopes will need to be
analyzed for stability. In the process, the soil embankment is also reinforced with geotextiles to
minimize the occurrence of landslides. This study was analyzed by modeling embankment
variations of 4 meters, 6 meters, and 8 meters with geotextile reinforcement using the Plaxis V20
program. For calculations on the original soil conditions were analyzed by the fellenius method.
The results of embankment stability analysis in the original soil condition with geotextile
reinforcement using the Plaxis V20 program during the construction period obtained the safety
factor for the 4-meter embankment without earthquake load of 1.893, the 6-meter embankment
load of 1.637, and the 8-meter embankment load of 1.622. While in post-construction, the safety
factor for the 4-meter embankment without earthquake loads of 1.651, the 6-meter embankment
load of 1.572, and the 8-meter embankment load of 1.512. For the analysis settlement of the
original soil condition with geotextile reinforcement for the calculation of excess pore water
pressure on a 4-meter embankment, the settlement has a value of 0.207 meters with a time of 88
days, a 6-meter embankment has a value of 0.434 meters with a time of 104 days, and an 8-meter
embankment has a value of 0.639 meters with a time of 131 days. | en_US |
