| dc.description.abstract | Failure of slope constructions might cause substantial
consequences for the environment and the surrounding
communities. Therefore, accurate analysis is required to identify
factors that affect slope stability. Terracing is suitable for hilly
areas with limited access, while geotextiles function to reinforce
soil and reduce the risk of slope failure. Geotextiles have
advantages in terms of workability and economic aspects. The aim
of this study is to analyze the influence of terracing variations and
the use of geotextiles on slope stability, as well as to compare the
results of slope geometry design analysis using numerical
calculations with the GeoStudio program. The research result
shows that the increase in the safety factor (SF) due to the addition
in the number of terraces from 2 terraces to 3 is 13.95%; from 3
terraces to 4 is 11.26%; from 4 terraces to 5 is 10.12%. The
increase in SF value due to the use of geotextiles on a slope with
2, 3, 4, and 5 terraces are 77.29%, 56.12%, 41.37%, and 32.17%,
respectively. The increase in SF value due to the addition in the
number of terraces and the use of geotextiles from 2 terraces to 3
is 0.34%; from 3 terraces to 4 is 0.74%; and from 4 terraces to 5
is 2.95% | en_US |
