| dc.description.abstract | One of the issues in constructing a structure is the presence of soft
subgrade soil. The purpose of this study is to examine the impact of
subgrade soil density on slope stability through geotextile reinforcement.
The variations of subgrade soil in this research include a 1 m replacement
using fill soil, a 2 m replacement using fill soil, a 1 m replacement using
fill soil and 1 m using limestone, a 1 m replacement using substitute
subgrade soil, a 2 m replacement using substitute subgrade soil, and a 1
m replacement using substitute subgrade soil and 1 m using limestone.
The slope stability analysis was conducted using the SLOPE/W program
in GeoStudio. The analysis results indicate that the slopes without
reinforcement and with variations in subgrade soil density do not yield
safe safety factor values. As the subgrade soil becomes weaker, the safety
factor decreases. The variation of 1 m replacement using substitute
subgrade soil and 1 m using limestone with reinforcement produces the
highest safety factor value, which is 1,84. | en_US |
