Abstract

Some damages of the Jalan Lintas Selatan Road, Suradita-Kranggan has occured every year with the identical failure cycle. One of the effort to make problem solving is to replace the base of road body construction with a concrete plate construction supported by circular pre-stressed concrete pile foundation (spun pile) system. The system will carry on the upper structure or embankment (subgrade) since the below of the structure exists soft soil layers and the depth of hard layer soil reachs more than 10 m. Later on, all vertical and horizontal forces including moments caused by the external loads can be retained by the plate and spun pile foundation system. The purpose of the study is to calculate the bearing capacity, negative friction force, settlement of spun pile group with using field test data (SPT and CPT); and diameter variation of pile is 30 cm to 50 cm. From calculations with the average length of 1400 cm and diameter of 50 cm can be determined bearing capacity of 298.9 tons by SPT and 504.3 tons by CPT data, respectively. Then, lateral bearing capacity is 168.5 tons (free pile head) and 344.2 tons (fixed pile head). The settlement occurred of a single pile foundation is 9.40 cm. The results of negative friction resistance were obtained is 81.9 tons. The group piles is designed of 2 (two) rows and 3 (three) columns and can be safe for receiving the construction and traffic loads. Based on the analysis results, the concrete plate and spun pile system has fullfilled to design criteria. Keywords: Spun Pile, Bearing Capacity, Negative Friction, Settlement, Pile Group.

Abstract

Pile is a deep foundation types of system always used to support a bridge abutment in a highway line. Pile foundation as one part of the sub-structure system can retain and transfer all loads from the upper structure. According to government standard regulation, a configuration of pile foundation must be selected and serve all external lateral loads in safety limits according to government standard regulation, including static and dynamic loads. This study evaluates the lateral stability of bridge abutment at the Indrapura Kisaran Toll Road section 2 at STA. 153 + 509, which designed using prestressed round pile foundations. Broms solution is a selected method to evaluate the lateral stability of a single and or group of pile foundations embedded in sand or sandy layers. From some design calculations, a configuration of 40 piles with a diameter of 50 cm shows adequately strong to resist all the lateral forces at the field. Keywords: Foundation, Piles, Sand.

Abstract

The high embankment is one of the most common problems in toll road construction projects. Embankment aims to equalize the ground elevation. Higher the embankment, the greater the load will be received by the subgrade. So, it is necessary to analyze the stability of the embankment to determine condition of stability and some important safety factor (SF) values. Slope stability planning was carried out using reinforced retaining wall with a height of 9,5 m and a width of 5,7 m. Soil foundation type was cohesive soil (clay) and the embankment soil type used non-cohesive soil (sandy). Several SF values are obtained by using Plaxis 8.2, such as: the safety factor (SF) of slope stability without and with reinforcements are 1,23 and 1,59, respectively; SF of shear stability is 2,24; SF of overturning stability of 2,1; and SF of bearing capacity is 3,36. Keywords: Plaxis 8.2, Retaining Wall Stability, Slope Stability.

Abstract

Road or highway system as an important part for development infrastructure program is a very critical and crucial problem for increasing the people's economic resources. Traffic of people and goods would have some disturbances if the road service damaged. One of main problems out of order the road is a groundwater movement in uncontrolled condition at study area. Therefore, a method of ground improvement has to be implemented at the road margin area. This study is going to focus on a couple model of construction systems implemented to avoid all slope sliding factors. From some laboratory and field data observations, clay layers as soil foundation during the road life time service plan at the study site indicated that there were some reductions of soil shear strength due to cohesion (c) values decreased. Fast alteration of water content (w) was the main cause of failure and defect of cohesion parameter, especially for expansive soil layers. From stability analysis using some geotechnical data and calculated by PLAXIS application software, the existing slope sliding was found in unsafe condition with safety factor (SF) ≤ 1.25. However, one option of design criteria using a couple construction model was obtained the better of safety factor with (SF) > 1.25.

Abstract

The most fundamental of unsaturated soil is matric suction parameter. Matric suction in unsaturated soils plays an important role in controlling physical and mechanical properties. This parameter can influence some other important parameters of soil, such as effective stress, shear strength, swelling pressure, etc. Investigation of matric suction was performed on Ayer Hitam soil, at Batu Pahat District, Johor, Malaysia. Field monitoring works were conducted with and without dolomite treatment at the slopes of Ayer Hitam acidic soil. Field testing used some devices to find out the behavior of matric suction during the rainy session. The result shows that the soil matric suction with dolomite treatment is larger than without treatment and matric suction has a significant difference around 20 – 50 kPa. Enhancement of acidity from the dolomite treatment was not only decreasing pores size caused by the alternating of the microstructure of soil but also leading to increasing the matric suction. The treatment of dolomite material is able to control matric suction and increase the stability of slope acidic Ayer Hitam soil.

Abstract

The Serang-Panimbang Toll Road Construction Project is one of the National Strategic Projects (PSN) with a total length of 83,677 km. The main bridge 18, which is one of the projects on the toll road section, has a drill pile foundation for its substructure. The drill pile foundation is a pile foundation that is installed by drilling the ground first, then filling it with reinforcement that has been assembled and cast in concrete. The foundation has a slope that is less than the permitted slope to support the load above it and is built to withstand both vertical and horizontal stresses. This study compared the Reese & Wright method with the Meyerhof method, two bearing capacity estimation techniques. The comparison aims to determine whether the outcomes of the two approaches utilized significantly differ from one another. The findings of the SPT test were used to conduct the analysis of bearing capacity. In this work, drill piles with a 1 m diameter and 15 m depth were used. According to the analysis's findings, the permit's bearing capacity using the Reese & Wright approach was 246.20 tons, however the permit's bearing capacity using the Meyerhof method was found to be 541.87 tons. For the Reese & Wright approach, the single drill pile decreased by 9,07 mm, and the group pile decreased by 25,7 mm; for the Meyerhof method, the single drill pile decreased by 9,17 mm, and the group pile decreased by 25,34 mm. Furthermore, it was found from both methods of calculating the bearing capacity that both stable static loads and dynamic loads work so that the foundation can be categorized (P max < Q single permit). The ratio of the bearing capacity of the single mast permit on the Reese & Wright method compared to the Meyerhof method is 0.478:1. Keywords: Bearing Capacity, Drilled Pile, Stability.

Abstract

Terdapat tiga konsep desain oprit jembatan yang berbeda pada saat mendesain jembatan layang Deltamas di Kota Bekasi, yaitu slab on spun pile, slab on bored pile, dan slab on bored pile. Dengan adanya variasi pilihan desain tersebut, analisis detail pergerakan struktur harus dilakukan sebelum rencana struktur oprit jembatan layang Deltamas dapat dibuat. Arah lateral dianalisa dengan menggunakan metode p-y curve, sedangkan desain slab on spun pile dan bored pile dianalisa dengan menggunakan metode elemen hingga. Daya dukung aksial dianalisis dengan menggunakan metode Mayerhoff. Pada kedalaman 24 meter dan 8 baris tiang berdiameter 0,6 meter, slab on spun pile memiliki daya dukung yang cukup dan defleksi maksimum tiang pada permukaan adalah 9,09 mm. (< 25mm), namun diperlukan perkuatan. Sementara itu, slab on bored pile memiliki daya dukung yang cukup pada kedalaman 28 m dengan 5 baris tiang berdiameter 0,8 m, dan nilai defleksi maksimum tiang pada permukaan adalah 9,44 mm (< 25 mm). Penulis menyarankan alternatif desain Slab on Bored Pile untuk berbagai faktor, termasuk stabilitas struktur.

Abstract

The foundation is an important part of the building, especially on the bridge that serves to withstand the load either its own weight or the load that works on it. The bearing capacity of the soil is the main support for a foundation as a component that transmits the load acting on the soil. Based on the results of the analysis of the bearing capacity of the drilled head of the bridgehead of the X toll road project, which was planned by the author with a configuration of 15 poles with a diameter of 100 cm at a depth of 20 m, the Ascial bearing capacity of 207,703 for single piles and 2429,674 tons for groups was obtained based on the Resse and Wright method. Meanwhile, the lateral bearing capacity is 249,206 tons for single-clamp conditions and 2915,159 tons for group piles using the Broms method. The decrease that occurred was 1,805 cm for single piles and 2,199 cm for group piles, and based on the calculation of stability, the configuration was said to be stable to withstand the working load.
