Analysis of Calculation of the Capacity of Jacked Pile Foundation 30 cm x 30 cm in the construction project of the Pramita Medan Clinic Laboratory Hospital

The foundation is a crucial component of a building that plays a vital role in distributing the load from the structure to the soil and rocks below. Therefore, the carrying capacity of the foundation must be carefully calculated to ensure that the building is stable and does not experience a decrease that exceeds the allowable limit. In the construction project of the Pramita Medan Clinical Laboratory Hospital, the analysis of the carrying capacity of the Jacked Pile foundation measuring 30 cm x 30 cm is carried out using various technical methods and data.

Understanding the Importance of Foundation Capacity Calculation

The foundation is the base of a building that transfers the weight of the structure to the soil and rocks below. A stable foundation is essential to ensure the safety and durability of a building. The carrying capacity of the foundation is a critical factor that determines its ability to withstand the load received from the structure. A foundation with inadequate carrying capacity may lead to structural damage, settlement, or even collapse. Therefore, it is essential to calculate the carrying capacity of the foundation accurately to ensure that it can support the weight of the building without experiencing excessive decreases.

METHODOLOGY CALCULATION CAPACITY

In this project, the carrying capacity of the pile foundation is evaluated through several methods, including sondir data, test standard test (SPT), HSPD 320 T manometer reading, and analysis using the Plaxis 8.6 program. Calculation of Lateral carrying capacity of the Jacked Pile foundation is carried out by the Broms method which is one of the commonly used methods to determine the lateral carrying capacity of the piles.

Sondir Data Analysis

Sondir data is a type of soil investigation that involves the use of a sondir tool to collect data on the soil's physical properties. In this project, the sondir data is used to determine the carrying capacity of the pile foundation. The data collected from the sondir test is then analyzed to determine the soil's bearing capacity, which is a critical factor in determining the carrying capacity of the foundation.

Standard Test (SPT) Analysis

Standard Test (SPT) is a type of soil investigation that involves the use of a standard penetration test (SPT) to collect data on the soil's physical properties. In this project, the SPT data is used to determine the carrying capacity of the pile foundation. The data collected from the SPT test is then analyzed to determine the soil's bearing capacity, which is a critical factor in determining the carrying capacity of the foundation.

HSPD 320 T Manometer Reading Analysis

HSPD 320 T manometer reading is a type of soil investigation that involves the use of a manometer to collect data on the soil's physical properties. In this project, the HSPD 320 T manometer reading data is used to determine the carrying capacity of the pile foundation. The data collected from the manometer reading test is then analyzed to determine the soil's bearing capacity, which is a critical factor in determining the carrying capacity of the foundation.

Plaxis 8.6 Analysis

Plaxis 8.6 is a type of software that is used to analyze the behavior of soil and rock under various loading conditions. In this project, the Plaxis 8.6 software is used to determine the carrying capacity of the pile foundation. The data collected from the Plaxis 8.6 analysis is then used to determine the soil's bearing capacity, which is a critical factor in determining the carrying capacity of the foundation.

Calculation Results

The analysis shows that the axial carrying capacity of a single pile varies greatly depending on the method used. Based on SPT data, the carrying capacity is recorded at 1007.8 tons. Meanwhile, data from Sondir produced a value of 103.7 tons, manometer reading showed 114.27 tons, and plaxis 8.6 analysis gave a value of 111.9 tons. A significant difference in this carrying capacity confirms the importance of choosing the right method for the calculation of carrying capacity.

Axial Carrying Capacity

The axial carrying capacity of a single pile is a critical factor that determines its ability to withstand the load received from the structure. In this project, the axial carrying capacity of a single pile is determined using various methods, including SPT, Sondir, manometer reading, and Plaxis 8.6 analysis. The results of the analysis show that the axial carrying capacity of a single pile varies greatly depending on the method used.

Lateral Carrying Capacity

The lateral carrying capacity of a single pile is a critical factor that determines its ability to withstand the load received from the structure. In this project, the lateral carrying capacity of a single pile is determined using the Broms method. The results of the analysis show that the lateral carrying capacity of a single pile is 16.66 tons, while graphically reaches 20.14 tons.

Efficiency Analysis

In addition, efficiency analysis is also carried out using two methods, namely Converse Labarre and Los Angeles Group. The efficiency of the Converse Labarre method is 0.76, while the Los Angeles Group method shows a value of 0.83. Based on this efficiency comparison, the smallest value is taken from the Converse Labarre method, which shows that although this efficiency value is not optimal, this method can provide more conservative and safe results to use.

Conclusion

From the analysis that has been carried out, it can be concluded that the calculation of the carrying capacity of the Jacked Pile foundation in the construction project of the Pramita Medan Clinical Laboratory Hospital is very dependent on the method used. Each method gives different results, so that the selection of the right method and relevant to the field conditions becomes crucial. The importance of this calculation is to ensure that the foundation can withstand the load received without experiencing excessive decreases, which can affect the overall stability of the building. Through careful data collection and in-depth analysis, it is hoped that this development project can run smoothly and safely.
