Abstract

The soil condition on the Rengat - Pekanbaru Toll Road Sta 193+ 025 - Sta 193+400 which passes through oil palm plantations, swamp areas, and the Siak River, consists of a compressible layer as thick as 7.0 meters. To handle the problem, a 375 m long slab on pile construction was planned with a construction time of 3 months. However, the design was costly; therefore, alternative planning using ordinary piles and a combination of ordinary and lightweight piles was required. The rate of settlement at the study site did not meet the requirements for t = 1 year (< 2cm/year) or t = 10 years (< 10cm/10 years). Therefore, it is necessary to install PVDs with an installation distance of 1.0 meter and a length of 7.0 m. The stability analysis showed that as the percentage of foam mortar increases, the SF value increases. The bearing capacity of the subgrade was increased by installing geotextiles; the number of geotextile layers required at each site varied depending on the height of the embankment and the combination of soil + foam mortar, the thicker the foam mortar, the less geotextile layers were required. The number of reinforcing piles was also planned according to the thickness of the soil and foam mortar variations; the thicker the foam mortar, the less piles were required. In terms of cost, the slab on pile replacement structures that provide savings are geotextile-reinforced soil backfill and a combination of soil backfill with 25% thick foam mortar. Each of these replacement structures provides savings of Rp 40 billion (without foam mortar) and Rp 12.1 billion (with 25% thick foam mortar). For the implementation time, both methods require the same completion time as slab on pile which is 3.5 months.

Abstract

The Probolinggo – Banyuwangi Toll Road, part of Trans Java Toll Road, is one of the strategic projects which connects the west to the east of the island of Java. On this toll road, precisely in section 3 STA 23+075 – 23+670, the toll road structure and pavement construction stands on soft ground with varying depths, with the deepest point being around 9 meters. It is concerned that the presence of soft soil which is quite deep will cause damage to the pavement, which will cause discomfort for road users if the soft soil cannot be improved properly. In this study, several alternatives are designed which will later be used as considerations for the project owner to determine the most effective method for improving soft soil at that location. The method used is subgrade replacement which will later be compared with the use of PVD along with estimated costs for each method. Apart from that, an analysis was also carried out regarding compliance with the rate of residual settlement regulations from the Director General of Highways, namely less than 2 cm per year and less than 10 cm per 10 years. From the study results, it was found that the rate of settlement of all variations of soft soil and replacement had met the Bina Marga regulations. In addition, a comparison of PVD cost requirements with replacement showed that PVD requires lower costs than replacement with a maximum time of ±5 weeks so that it can be concluded as the best alternative method.

Abstract

The trans-Sumatra toll road project currently under construction is the Rengat - Pekanbaru toll road construction project, the Pekanbaru ring road section located at km 205 + 150 to km 205 + 725 (575m long). In this section, quite deep excavation work is required as well as quite wide land acquisition which causes expensive land acquisition costs. In this study, slope variations were carried out with steeper angles in order to obtain a smaller road ROW; only additional reinforcement needs to be planned so that the slope is more stable and does not cause landslides. The stability of the varying slope slopes was analyzed using an auxiliary program to obtain the safety factor for each selected slope. In conducting the analysis, the elevation of the groundwater level was varied, namely at the bottom of the excavation (conditions during the dry season), as in secondary data, and at the top of the excavation (conditions during maximum rainfall). Slope stability analysis was also carried out using the ' theory of cracked soil' approach. Slope reinforcement using ground anchors will be planned if SF <1.0; for slopes that have SF ≥ 1.0, rainwater management will be carried out without reinforcement. The excavation slope at Sta 205+400 with a slope of 1:2 and 1:3 and the groundwater level at the top of the excavation is SF = 1.73; if the analysis is carried out using the cracked soil approach, the safety factor value drops to SF = 0.68. In addition, in the alternative slope gradients, namely alternative 1 with a slope angle of 1:1 and alternative 2 with a slope angle of 2:1, the slope safety factor changes quite drastically to 0.39 in alternative 1 and 0.2 in alternative 2. The cost calculation for alternative 2 with a slope gradient of 2:1 saves excavation work of 183,136.31 m3, 34,375 m2 of land acquisition and reinforcement costs of 3,422 Ground anchor points in cracked soil conditions and groundwater elevation with existing conditions of secondary data.

Abstract

The Singaraja - Pengayaman BTS Road Section is a national road located in the central corridor of Bali Island and includes several critical locations in terms of road geometry. Geometric adjustments are being addressed through the BTS Singaraja - Mengwitani Road and Bridge Construction Project Section 7E, involving excavation work up to 64 meters high at STA. 0+119.87. This study aims to analyze slope stability based on existing conditions, evaluate the impact of excavation method variations on slope stability, and determine effective excavation methods both with and without the influence of water on slope stability using Plaxis 2D program. The research results indicate that the safety factor (SF) value of the existing slope prior to excavation was 1.337, whereas it decreased to 1.034 after the final excavation stage. According to the SNI 8460:2017 standard (SF < 1.5), the slope condition in the final excavation stage is deemed unsafe. Excavations with depth variations of 1 meter, 2 meters, and 3 meters, as well as at slope angles of 45˚, 55˚, and 65˚, showed similar impacts on slope stability. A significant decrease in the safety factor occurred from the 7th excavation bench downward, where the safety factor fell below 1.3. At the end of the excavation process, the deepest sliding surface reached a depth of 20.11 meters. At an elevation of +36.5 meters, where the groundwater level reaches 56.40% of the total slope height, which marks the boundary between soil and rock layers, the safety factor drops to 1.040. Further increases in groundwater levels above +36.5 meters could render the slope unstable and potentially lead to collapse.

Abstract

The Lombok International Airport – Mandalika Bypass Road experienced a landslide at KM 10+415 to 10+519 in February 2023 during heavy rainfall. The landslide is estimated to have occurred due to the saturation of the embankment caused by groundwater flow and rainwater infiltration. The proposed reinforcement includes the use of foam mortar with thickness variations of 2m, 4m, and 6m, with or without subdrain. Another proposal involves using Rigid Inclusions in the form of controlled modulus columns (CMC) with column spacing variations of 2ø, 3ø, and 4ø, with or without subdrain. Numerical analysis of the safety factor (SF) and deformation (Uy) was conducted using the Plaxis 2D program, both for the initial condition and after reinforcement. In general, the SF and deformations (Uy) for all reinforcement variations meet the reinforcement criteria, i.e., SF > 1.5 and deformations (Uy) < 2cm. The smallest SF of 1.579 was obtained with 4m thick foam mortar with subdrain. The largest deformations (Uy) of 1.656 was found with 2ø column spacing CMC without subdrain. The most effective Stress Reduction Ratio of 0.13 was achieved with 2ø column spacing CMC without subdrain. The influence of the subdrain is not significant because the landslide surface did not reach the groundwater table.
