Feb 27, 2025 by ADMIN 103 views

Introduction

Pole foundation is a crucial structure in development, particularly on land that lacks sufficient carrying capacity to support the burden of buildings. Ensuring the stability of the building is vital, and the calculation of carrying capacity and decrease in piles is a critical aspect of this process. This study aims to analyze the carrying capacity and decrease of piles in the WTP Extension Project DS Limau Sweet Tanjung Morawa, utilizing analytical methods and Plaxis software v.8.6.

Background

The WTP Extension Project DS Limau Sweet Tanjung Morawa is a significant development project that requires careful planning and execution. The project's success depends on the stability of the building, which is directly related to the carrying capacity and decrease of piles. The carrying capacity of a pile refers to its ability to support loads without failing, while the decrease of piles refers to the settlement or movement of the pile over time. Understanding these factors is essential to ensure the building's stability and safety.

Research Methods

This study employed a combination of analytical methods and Plaxis software v.8.6 to analyze the carrying capacity and decrease of piles. The research methods used in this study include:

Data collection: Field observation and data collection from consultants and companies were conducted to gather relevant information.
Calculation of axial carrying capacity: The Mayerhof, Calendar, ENR, Danish, and element methods were used to calculate the axial carrying capacity of a single pile.
Calculation of lateral carrying capacity: The Broms method was used to calculate the lateral carrying capacity of a single pile, both analytically and graphically.
Decreased elastic single piles: Analytical and Plaxis methods were used to calculate the decreased elastic single piles.
Decreased Poulos and Davis: This method was used to calculate the decreased Poulos and Davis to obtain a more comprehensive picture.

Pore Pressure

Before consolidation: -10.64 kN/m2
After consolidation (element method until): -10.32 kN/m2
Consolidation time (element method to): 0.9 days

Discussion

The difference in results can be associated with several factors, including:

Types of Soil

Variation of soil types at the project site can affect the carrying capacity and decrease piles.

How to Carry Out Testing

The accuracy of the operator in the implementation of SPT testing can affect the value obtained.

Calculation Parameters

The difference in parameters used in the calculation of each method can cause differences in results.

Conclusion

This study demonstrates that the use of analytical and software methods such as Plaxis V.8.6 can provide different results in the analysis of carrying capacity and decreased piles. This difference needs to be considered and carefully considered to determine the most appropriate method for a particular project. It is also necessary to do a more detailed and comprehensive analysis by considering the factors that can affect the carrying capacity and decrease piles, such as soil types, groundwater conditions, and loads that work on piles.

The results of this study are expected to be a consideration for practitioners and designers in determining the most appropriate analytical method for development projects in the land with similar conditions.
