| dc.description.abstract | The Balikpapan-Samarinda Toll Road project is located in East
Kalimantan Province. The project site consists of soft soil, which presents
a potential risk of soil. To mitigate and eliminate this risk, it is essential to
analyze the slope stability of the embankment constructed on the soft soil.
The stability analysis of the embankment slope is conducted using the
SLOPE/W Geostudio 2018 software, employing the limit equilibrium
method. The modelling and analysis process focuses on both the left and
right sides of the embankment slope due to the asymmetric shape of the
slope's base. The stability analysis involves considering various loading
conditions, such as traffic loads and structural loads with and without
seismic loads. According to the analysis results obtained using SLOPE/W
Geostudio 2018 R2, the embankment slope, with a height of 7,35 m, exhibits
SoF values that satisfy the required criteria in different loading
combinations. For the left side, the SoF value is 1,498 when considering
traffic and structural loads without seismic loads, and 1,311 when factoring
in seismic loads. On the right side, the SoF values are 1,842 when
considering traffic and structural loads without seismic loads, and 1,632
when factoring in seismic loads. While the embankment slope on the right
side meets the required safety of factor (SoF > 1,5), the left side necessitates
reinforcement using geotextiles. By implementing geotextiles with an
ultimate tensile strength of 55 kN/m, the left embankment slope achieves a
SoF value of 1,506, satisfying the required criteria. | en_US |
