Abstract

Slope stability analysis of Komering River in Ogan Komering Ilir, South Sumatra was done to handle the problem of sliding or scouring at the cliffs which are often found on the outside corner of the river. Komering River is a river with meandering pattern that is very susceptible to scouring on the outside of the bend and sedimentation on the inside of the bend. This research focuses on the study of slope stability analysis with sheet pile used as method. Analysis was conducted using Geostructural Analysis version 19 and was compared to manual calculation.Data analysis on the result of soil testing was performed to identify soil properties. The obtained results were then used in slope stability analysis. Slope stability analysis was performed in two conditions maximum groundwater level and normal groundwater level using Bishop method and Fellenius method. The results of manual calculation were then compared with the results of Geostructural Analysis Program Version 19. Sheet pile was selected as slope stabilization measures. Analysis after stabilization is done with the same steps as analysis before stabilization.The results from the two methods showed a quite significant difference. The results obtained from Bishop method before stability measure and after stability measure were 1,018 and 4,23 respectively. Whereas, the results obtained from Fellenius method before stability measure and after stability measure were 0,75 and 3,42 respectively. Based on these results, it can be concluded that sheet pile is an effective slope stability measure.Keywords: Slope stability, Geostructural Analysis Program, Bishop, Fellenius, Sheet Pile.

Abstract

Soil sample that used as base material in this study was taken from Belimbing Sari Village area, Sub Jabung, East Lampung. Based on the testing of soil physical's characteristics, USCS classified soil samples as organic soil with medium to high plasticity and belongs to the OH group. The mixed content which used in this study was 85% soil, 10% lime, and 5% cement with curing time for 14 days, then it was divided with combustion and without combustion treatment on the paving block sample and soaked for 4, 8, 12, and 16 days. The result of this study was to obtain the average value of pressed-value on a mixture of 85% soil + 10% lime + 5% cement after the largest burning treatment and soaked for 4 days at 11.7 MPa. Thus, in addition to the combustion, the duration of immersion also affects its pressed-value. The longer it had soaked, the smaller its pressed-value would be. Therefore, this pressed-value met the requirement of the paving blocks' SNI-03-0691-1996 that was qualified on the classification of quality D which had the average pressed-value of at least 10 MPa. In addition to the pressed-value, the water absorption rate which was 15.5% -20.32% did not meet the paving blocks' requirement of SNI-03-0691-1996.Key words : Paving block, organic clay soil, compressive strength, water absorption, immersion.
