The Importance of Foundation Planning

Oct 13, 2025 by miodeya.com 13 views

Introduction

The foundation is a vital component in building construction, playing a crucial role in transmitting the burden of the building to the ground. To ensure building stability, foundation planning must be meticulous, considering various factors such as building loads, soil nature, and potential external forces. The Medan-Binjai toll road construction project, Section I (STA 2+000), on Jalan Veteran, involved the analysis of the carrying capacity of the P3'-N25 pile pile foundation. This analysis was carried out using analytical and numerical methods to determine the ability of the foundation to hold the load.

The Importance of Foundation Planning

Foundation planning is a critical aspect of building construction, as it directly affects the stability and safety of the structure. A well-designed foundation can ensure that the building remains stable and secure, even in the face of external forces such as earthquakes, floods, and soil settlement. On the other hand, a poorly designed foundation can lead to structural damage, collapse, and even loss of life. Therefore, it is essential to carefully consider various factors when planning a foundation, including building loads, soil nature, and potential external forces.

Analytical Method

The analytical method involves using mathematical formulas and equations to determine the carrying capacity of the foundation. Several methods can be used, including:

Meyerhof Method

The Meyerhof method is based on Standard Penetration Test (SPT) data and produces the carrying capacity of ultimate piles. This method is widely used in foundation design and has been shown to be effective in determining the carrying capacity of piles.

Danish Method

The Danish method relies on calendar data and provides a carrying capacity of 808.88 tons. This method is also widely used in foundation design and has been shown to be effective in determining the carrying capacity of piles.

ENR Method

The ENR method also uses calendar data and produces a carrying capacity of 690.33 tons. This method is similar to the Danish method and has been shown to be effective in determining the carrying capacity of piles.

Janbu Method

The Janbu method uses calendar data and produces a carrying capacity of 531.62 tons. This method is also widely used in foundation design and has been shown to be effective in determining the carrying capacity of piles.

Broms Method

The Broms method is used to calculate the lateral carrying capacity of the pile and produces an analytical value of 54.36 tons and 54.02 tons graphically. This method is widely used in foundation design and has been shown to be effective in determining the lateral carrying capacity of piles.

Numerical Method

The numerical method involves using computer programs and software to determine the carrying capacity of the foundation. Several methods can be used, including:

Element Method to (Plaxis)

The element method to (Plaxis) is a computer program that produces a carrying capacity of 241.46 tons, a decrease for 6 days. This method is widely used in foundation design and has been shown to be effective in determining the carrying capacity of piles.

Comparison and Analysis

The significant difference in the results of the calculation of the carrying capacity of various methods can be explained by several factors, including:

Different Test Points and Depth

Testing location and different soil depth can produce significant variations of soil types and properties. This can affect the results obtained from the different methods.

Human Error

Errors in the testing process in the field can affect the results obtained. Human error can occur during the testing process, and this can affect the accuracy of the results.

Parameter Difference

Each method uses different parameters in calculations, so as to produce different results. This can affect the accuracy of the results obtained from the different methods.

Conclusion

Analysis of the carrying capacity of the foundation of the P3'-N25 pile shows the results that vary depending on the method used. Although there are significant differences, the results of calculations from SPT, PDA, calendar (Janbu method), and the method of elements to (plaxis) have similarities. This shows the importance of using a combination of methods to get a comprehensive picture of the carrying capacity of the foundation. This information can then be used to determine a safe and optimal foundation design, ensuring building stability and resistance in the long run.
