Analysis of Bored Pile Foundation Carrying Capacity Using Analytical Methods and Plaxis Software: Case Study of Medan Railway Flying Roads - Bandar Khalipah Km 0+600

Introduction

The foundation is a vital element in the construction of civil engineering projects, as it serves to channel and withstand the loads working on it, such as the burden of the building structure. In the train overpass construction project carried out by the Directorate General of Railways in the middle of the dense Medan city, the selection of the Bored Pile foundation is the right choice. This is because the use of piles can risk damage to buildings around the location. In addition, the design with a large pole diameter is also needed in order to withstand the load well.

The selection of the right foundation type is crucial in ensuring the safety and structural resistance of the project. In this case, the Bored Pile foundation is chosen due to its ability to withstand the load well and minimize the risk of damage to surrounding buildings. However, the design and analysis of the foundation are equally important in ensuring its carrying capacity and safety.

This study aims to analyze the axial carrying capacity of the bored pile foundation based on the Standard Penetration Test (SPT) data, using several methods, namely the Reese and Wright method and the element method to use the Plaxis software. In addition, the analysis was also carried out to calculate lateral carrying capacity by the broms method, as well as analyzing elastic decreases that might occur in bored piles.

Data Methods and Collection

The data used in this study were obtained through field observations and data collection from the North Sumatra Railroad Engineering Center. Calculation of the carrying capacity of the axial bore pole is carried out using SPT data. The calculation results show that with the Reese and Wright method, the axial carrying capacity produced is 1486.77 tons at a depth of 33 meters. In addition, the results of the PDA (Pile Driving Analyzer) test indicate the carrying capacity of the ultimit at the same depth of 822.90 tons. The analysis using plaxis software shows the axial carrying capacity of 852.63 tons at the same depth, showing consistency in the calculation results.

The use of SPT data in calculating the carrying capacity of the bored pile foundation is a common practice in the industry. However, the accuracy of the results depends on the quality of the data and the method used. In this study, the Reese and Wright method is used, which is a widely accepted method in the industry. The results show that the axial carrying capacity of the bored pile foundation is 1486.77 tons at a depth of 33 meters.

Lateral Carrying Capacity and Decline

Lateral carrying capacity analysis is carried out by the Broms method, which produces a value of 157.50 tons analytically and 128.53 tons graphically in the bore hole - 20. The resulting elastic decrease is 20.05 mm, while the analysis using the plaxis software shows a decrease amounting to 5.36 mm. The difference between the results of this analysis shows the importance of choosing the right calculation method and relevant to the conditions in the field.

The lateral carrying capacity of the bored pile foundation is an important factor in ensuring its safety and structural resistance. The Broms method is widely used in the industry to calculate the lateral carrying capacity of bored piles. However, the accuracy of the results depends on the quality of the data and the method used. In this study, the results show that the lateral carrying capacity of the bored pile foundation is 157.50 tons analytically and 128.53 tons graphically in the bore hole - 20.

Conclusion

From the overall method of calculating the carrying capacity and decrease that occurs due to the workload on the bored pile foundation, the results of the analysis show that this foundation is still in the safe category. The results of this study provide important information for the planning and implementation of construction projects in densely populated areas such as Medan, as well as emphasizing that the use of modern technology such as analysis software can help in more accurate and efficient calculations.

The importance of the analysis of the carrying capacity of the foundation like this not only contributes to the success of construction projects, but also ensures long-term safety and structural resistance.
