| dc.description.abstract | A slope is an inclined land surface from a higher point to a lower
point. Slopes are usually formed due to excavation for construction
or naturally formed due to landslides. Slope reinforcement is a way
to ensure stability and safety against landslides. One of the
commonly used reinforcement methods is the use of geotextiles. The
advantages of using geotextiles for reinforcement are ease of
implementation, cost-effectiveness, and the ability to enhance slope
stability actively. The stability analysis of slopes is conducted to
assess whether a slope is stable and safe from landslides. Slope
stability analysis can be performed using empirical or numerical
calculations. Numerical analysis is conducted using the GeoStudio
program. This research studies the influence of slope angles on the
safety factor. The analysis is performed using five different methods:
the Ordinary Method, the Bishop Method, the Janbu Method, the
Morgenstern-Price Method, and the Spencer Method in the
GeoStudio software. Based on the results obtained from three slope
angle variations (60°, 65°, and 75°) under a factory's live load and
using the five methods in the GeoStudio program, the slopes are
classified as unsafe with SF <1.5. After planning reinforcement with
Hibritex Geotextile LP75/75 and applying it to the slopes with the
three angle variations, the resulting safety factors are classified as
stable and safe with a safety factor >1.5. | en_US |
