Study Of The Loading Time In The Consolidation Test Of The Peat Soil Peat Seleng, The Upstream Labuhan Stone Blades
Introduction
Peat soil is a type of soil that has unique characteristics, but is often less supportive for civil building construction. High moisture content, low carrying capacity, and high compressibility are some of the main challenges in the use of peat soil as a foundation. This compression occurs due to deformation of soil particles and the discharge of water or air from the pores of the soil, all of which are influenced by the condition of the peat soil itself. Understanding the physical properties of peat soils and how this soil behaves under load is crucial in avoiding problems that may arise in the future.
Background of the Study
Peat soil is a type of soil that is formed from the accumulation of partially decayed plant matter. It is characterized by its high moisture content, low carrying capacity, and high compressibility. These characteristics make peat soil a challenging material to work with, especially in civil building construction. The use of peat soil as a foundation requires careful planning and implementation to avoid problems such as settlement, instability, and collapse.
Objectives of the Study
The main objective of this study is to determine the physical properties (index properties) of peat soils, determine the classification of peat soils, and calculate the value of compression index and coefficient of consolidation of peat soil based on gradual loading. In addition, this study also observed the use of edometer consolidation devices for peat soils. The results of this study will provide valuable information for civil engineers and planners in designing and constructing buildings on peat soil foundations.
Methodology
The study was conducted in the Tanjung Medan Labuhan Batu area, where peat soil samples were taken from the upstream Labuhan stone blades. The samples were then analyzed for their physical properties, including water content, specific weight, wet volume weight, dry volume weight, and pore number. The results were then compared to the ASTM D4427-84 (1989) standards to determine the classification of the peat soil. The edometer consolidation device was used to measure the compression index and coefficient of consolidation of the peat soil.
Results and Discussion
The results of the study showed that the peat soil samples had a fairly high water content, with an average of 455.31%. The specific weight was 1,287, with a wet volume weight of 1.387 gr/cm³ and a dry volume weight of 0.273 gr/cm³. The pore number generated from the test was 3,716. In accordance with ASTM D4427-84 (1989) standards, this soil sample was categorized as a low ash peat peat soil, with an ash content of 4.290%.
The analysis of the compression index showed varying results based on testing on two different samples. Sample 1 had a compression index (CC) of 0.660, while sample 2 was 0.640. Meanwhile, the consolidation coefficient (CV) also showed the difference, where sample 1 was recorded at 0.530 cm²/second and sample 2 of 0.787 cm²/second. These results indicate that the speed of peat soil reduction is very dependent on the amount of loading given.
Conclusion
The existence of peatlands that have special characteristics like this require a careful approach in the planning and implementation of construction. Understanding of the physical properties of peat soils, as well as how this soil behaves under load, is the key in avoiding problems that may arise in the future. Therefore, it is important for civil engineers and planners to consider this data in the structural design process in areas dominated by peat soils.
Recommendations
With a deeper understanding of the properties of peat soils, it is hoped that this study can be a reference in developing a more effective and safe construction technique for use on soil with this challenging characteristic. Further research is needed to develop a more comprehensive understanding of the behavior of peat soils under different loading conditions.
Limitations of the Study
This study has several limitations, including the limited number of samples used and the limited scope of the study. Further research is needed to confirm the results of this study and to develop a more comprehensive understanding of the behavior of peat soils.
Future Research Directions
Future research should focus on developing a more comprehensive understanding of the behavior of peat soils under different loading conditions. This can be achieved through further laboratory testing and field observations.
Conclusion
In conclusion, this study has provided valuable information on the physical properties of peat soils and how this soil behaves under load. The results of this study will provide a useful reference for civil engineers and planners in designing and constructing buildings on peat soil foundations.
