Abstract

Slope stability analysis is very important in slope design so it can manage and maintain the infrastructure assets. If the slope is unstable, it can damage the infrastructure around the slope. The method commonly used in slope stability analysis is 2D modeling which assumes the length of the landslide area is not limited or continuous. In fact, landslides that occur in the field are limited and not continuous, so 3D modeling is more suitable than 2D modeling. 3D slope stability analysis has been developed by various researchers. Most of the results of previous studies stated that the 3D and 2D factor of safety ratio was more than one for cohesive soils and less than one for non-cohesive soils. This safety factor affects the amount of reinforcement needed. Differences in 2D and 3D safety factors will cause differences in the amount of reinforcement needed. Therefore, this study was conducted to determine the differences in the 2D and 3D slope stability analysis result. Slope stability analysis was carried out using LEM, where the 2D slope stability used the Fellenius method while the 3D slope stability used the Hovland method. Calculate the required reinforcement amount using geotextiles with Tult = 250 kN/m. The results obtained from this study are the 2D safety factor is smaller than the 3D safety factor. The 3D and 2D safety factor ratios range from 1.09 – 1.397. While the amount of reinforcement required in the 3D analysis is less than in the 2D analysis with the ratio of 3D and 2D reinforcement requirements ranging from 0.5 to 0.955 depending on the width and height of the embankment.

Abstract

The infrastructure is importantfor the greatlife of a region and most of the country.Therefore, infrastructure must bealways in proper condition inits functionality. Furthermore, it must follow the main principlewhich isinfrastructure asset management. In this case, geotechnical mapping is also related to the principles of Infrastructure Asset Management in planning, designing, and feasibility studies of an infrastructure project in Badung Regency, hencethe infrastructure projects are better prepared. The research methodsincludecollecting soil investigation data, processing soil investigation data, describingthe results of soil investigation data with mapping tools, and geotechnical zoningwith statistical analysis. The results obtaina geotechnical map of Badung Regency in2 and3-dimensional forms.The 2D results in the form of a hard soil depth map can be concluded that South Kuta District has a variable depth of 0.4 –15 meters, North Kuta District has a variable depth of 1.5 –5 meters, Kuta District has a variable depth of 1.5 –10 meters, Mengwi District has a variable depth of 1.5 –10 meters, Abiansemal District has a variable depth of 5-15 meters, Petang District has a variable depth of 5-22 meters. The 3D Zone 1 lithology map can be concluded that the Zone 1 area covered with a hard soil depth of around 5 –10 meters is dominated by sandy silt, silty sand, sand, and a little clayey silt. That area covered with a hard soil depth of about 1.5 –5 meters is dominated by clay, clayey silt, sandy silt, silty sand, and sand with a heterogeneous distribution. The Zone 1 area is dominated by the specific volume saturated value (γsat) range of 1.5 –2.0 t/m3. The values > 2.0 t / m3 are found in Sading area with a hard soil depth of 5-10 meters. The Zone 1 area is dominated by the range of N-SPT values = 0 -30. The N-SPT values > 30 are found in Sading area with hard soil depths of 5-10 meters.
