Analysis of the Carrying Capacity of the Pile Foundation in Bore Hole 3: A Comparative Study of Analytical and Numerical Methods

Introduction

The construction of infrastructure projects, such as dams, requires a thorough and meticulous planning process to ensure the stability and resilience of the building. One crucial aspect of this planning process is the analysis of the carrying capacity of the pile foundation. The D.I Serdang Dam construction project is no exception, and in this article, we will delve into the analysis of the carrying capacity of the pile foundation in Bore Hole 3 using both analytical and numerical methods.

The Importance of Pile Foundation Analysis

The pile foundation is a critical component of any infrastructure project, as it transfers the weight of the building to the underlying soil or rock. The carrying capacity of the pile foundation is a measure of its ability to withstand the loads imposed on it, and it is essential to determine this capacity accurately to ensure the safety and stability of the building. In the D.I Serdang Dam construction project, the axial and lateral carrying capacity analysis in Bore Hole 3 is a critical aspect of the foundation planning process.

Methods and Calculation Results

Several methods were used to analyze the carrying capacity of the axial foundation of piles in Bore Hole 3, including analytical and numerical methods. The analytical methods used include Hiley, Danish, ENR, and SPT (Standard Penetration Test) data, while PDA data (pressuremeter test) was also involved. In addition, the element method up to the Plaxis program version 8.6 was used to obtain a numerical carrying capacity.

The calculation results show a significant variation in axial carrying capacity. The SPT method produced a value of 174.29 tons, while the Hiley, Danish, and ENR methods gave a value of 163.03 tons, 169.05 tons, and 194.82 tons, respectively. PDA data shows a value of 120.2 tons, while the element method produced a higher result of 233.1 tons.

For lateral carrying capacity analysis, the Broms method was used. Analytical calculation results produced a value of 8.81 tons, while graphically produced a value of 8.41 tons. The decrease in the foundation was calculated by the poulos and davis method, the elastic method of a single pole, and the method of element to, producing a value of 10.9 mm, 13.76 mm, and 19.18 mm, respectively.

Pole group efficiency was calculated by three different methods: Seiler-toey (0.797), Converse Labarre (0.843), and Los Angeles (0.871).

Factors Causing Differences in Yield

The difference in the value of carrying capacity and decrease obtained from various methods is caused by several factors.

Types of Soil

Soil characteristics in the location of Bore Hole 3, including the type, density, and other geotechnical properties, have a major effect on the carrying capacity of the foundation.

Depth of Review

Different calculation methods may consider different depths in the analysis, so as to produce different values.

Implementation and Human Accuracy

The process of soil testing such as SPT and PDA is very dependent on human accuracy, which can affect the final outcome.

Calculation Parameters

Each calculation method uses different parameters, such as soil elastic modulus, soil shear angle, and soil cohesion, which directly affects the final result.

Conclusions and Recommendations

Analysis of the carrying capacity of the pile foundation in Bore Hole 3 shows the need for the use of various methods for getting a more comprehensive picture. The difference in results obtained indicates the importance of considering the factors that influence the carrying capacity of the foundation, such as soil type, depth, and calculation parameters.

In planning construction, it is recommended to use a combination of analytical and numerical methods, as well as consider accurate soil testing results. In addition, consultation with geotechnical experts is very important to ensure optimal and safe foundation design.

Future Directions

Further research is needed to develop more accurate and reliable methods for analyzing the carrying capacity of pile foundations. This may involve the development of new calculation methods or the refinement of existing methods. Additionally, the use of advanced technologies, such as 3D modeling and simulation, may provide more accurate and detailed results.

Conclusion

In conclusion, the analysis of the carrying capacity of the pile foundation in Bore Hole 3 using both analytical and numerical methods has shown the importance of considering various factors that influence the carrying capacity of the foundation. The use of a combination of analytical and numerical methods, as well as accurate soil testing results, is recommended to ensure optimal and safe foundation design. Further research is needed to develop more accurate and reliable methods for analyzing the carrying capacity of pile foundations.
