| dc.description.abstract | The internal influences of slope instability, such as increased pore
water within the slope, water flow characteristics, and soil shear
strength, pose significant challenges in slope stability analysis
research. In addition to these factors, the groundwater level also
impacts slope stability. The influence of varying groundwater
levels will be examined in this study to determine the extent of its
effect on slope stability and the corresponding safety factors. With
the advancement of technology, slope stability analysis can be
conducted using applications as assisting tools, commonly known
as numerical methods in slope stability analysis. Geostudio is one
software specifically designed for accurate slope stability analysis.
The analysis process involves utilizing five methods available in
Geostudio, namely the Morgenstern-Price, Spencer, Bishop,
Janbu, and Ordinary methods. In this study, Geotextiles are
chosen as the slope reinforcement method. The parameters include
soil unit weight, internal friction angle, cohesion, Poisson's ratio,
and soil elasticity modulus. Based on the analysis results using the
methods mentioned earlier, for both unreinforced and reinforced
slope conditions and variations in groundwater levels, the most
significant safety factor (SF) obtained for the unreinforced slope
is 0.269 using the Morgenstern-Price method. At the same time,
the highest SF value of 2.503 is achieved for the reinforced slope
using the Bishop method. The significant increase in the safety
factor, approximately tenfold, as a result of geotextile
reinforcement proves its effectiveness in slope stabilization. | en_US |
