“…The SPT of the soil subgrade was tested along Section 2 and further divided into three models based on the properties indicated by the test. These models were based on the similar characteristics and consistency of the subgrade as reported by a previous study [1] and presented in Table 1.…”

“…Consequently, the safety factors for these manmade slopes on soft soil were analyzed to ensure stability. A previous study focused on determining the reinforcement design in the bridge abutments for a small part of the toll toad section [1] but there have been no studies conducted to comprehensively analyze the slope stability of the embankment.…”

The Pejagan-Pemalang toll road which is a Section II project was designed at different embankment heights on soft soil subgrade. The process involved investigating the slope stability of these embankments through the determination of the safety factor. This can be achieved using different methods such as the limit equilibrium method (LEM) and the finite element method (FEM) which are considered the standard approaches. However, the presentation of different numerous results for the safety factors (SF) in landslide calculations usually makes it difficult for the engineer to understand some uncertain conditions. Therefore, this study aims to determine the safety factors using LEM and FEM approaches at different conditions. The soil subgrade used was in SPT and three models of the properties were obtained. Moreover, a Geo-Studio program with Slope-W analysis was applied using the Morgenstern-Price for the LEM and PLAXIS for the FEM. The height was varied at 2 to 8m with the slope H: V at 1:1, 1:1.5, and 1:2. The simulation was conducted at three different levels of groundwater. The results showed that the height, embankment geometry, and groundwater levels were affected in the SF analysis using the two methods. It was also discovered in all categories that higher embankments had smaller SF while the higher angle of slope produced a higher SF. Furthermore, the properties of the soft soil were observed to have influenced the SF result as indicated by the narrow difference in the correlation between the embankment height and SF. The results of the LEM and FEM were also compared and the observations were explained. The findings of this study are expected to serve as a guide for engineers, especially those in road toll projects, to determine the optimum model needed to predict slope failure in embankments for toll roads.

“…The general slope reinforcement, such as sheet pile, retaining wall, and geogrid, was designed in this paper, considering the stiff consistency of the subgrade. This analysis has generated the safety conditions in another Toll Road project [6]- [12]. Consequently, this study aims to determine the proposed design that appropriates site conditions.…”

The Balikpapan - Samarinda Toll Road is a new infrastructure project that connects two capital cities in East Borneo. Landslides occur in sections 28+000 to 28+100, necessitating the terrace design to prevent unstable conditions. As a result, a new proposed design is required to ensure safety in this area. This study aims to offer further slope reinforcement in this location to prevent landslides. This research utilizes secondary data from Standard Penetration Test (SPT) results to determine the soil properties. First, the lateral earth pressure was conducted to calculate the sheet pile and retaining wall structure. The other reinforcement is geogrid with geotextile combine. The Finite element model carried out all the overall stability with Plaxis calculation. The results show that all new proposed to generate the safety factor value 1.3. Sheet pile variations present the CCSP type W-600 with a total length reaching 17m, which offers a safety factor 1.31. The second variation is a retaining wall with a full height of 5m and combined in sheet pile design, which reaches the safety factor in the overall stability of 1.498. the internal strength of the retaining wall is divided into three categories: overturning, sliding, and bearing capacity with 1.55, 2.44, and 2.88, respectively. Meanwhile, the geogrid type described the SF 1.32 with three step slope design and spacing of 0.3m, 0,5m, and 1,0m, respectively.
