Laboratory Investigation Of Hydraulic Conductivity Characteristics Of Fill Materials

Civil Engineering BEng (Hons)

Delve into the fascinating world of geotechnical engineering as we explore how gradation affects permeability in silica and carbonated sand. 

Brief Overview of the Project

My project focuses on studying the impact of gradation on the permeability of silica and carbonated sand, both before and after undergoing compaction or strength enhancement. Utilising entropy theory, I aim to predict changes in permeability based on variations in material gradation. This research is crucial for understanding how different particle arrangements affect fluid flow through geotechnical materials.

What Made You Want to Develop This Idea?

My interest in geotechnical engineering sparked my desire to delve into this project. I am fascinated by how soil properties influence its behaviour and performance in practical applications. The opportunity to explore the relationship between gradation and permeability, with guidance from industry professionals, further motivated me to pursue this research.

Why Is There a Need for What You’re Creating?

Understanding the relationship between gradation and permeability is essential in geotechnical engineering. It allows engineers to predict and control the flow of fluids through soil and other porous materials. By enhancing our knowledge in this area, we can improve the design and construction of foundations, embankments, and other geotechnical structures, leading to more efficient and sustainable engineering practices.

Can You Explain About the Kind of Equipment You Are Using, and How You Are Creating the Physical Product?

The equipment for this project includes instruments for measuring particle size distribution, such as sieve analysis and laser diffraction techniques. Additionally, tools for testing permeability, like permeameters, are crucial in determining how different gradations affect fluid flow rates through the materials.

To create the physical product, I am conducting laboratory experiments where silica and carbonated sand samples undergo controlled compaction or strength enhancement processes. These processes simulate real-world conditions and allow me to observe changes in gradation and permeability. Data from these experiments will be analyzed to validate predictions made using entropy theory.

Where Do You Envision the Future of This Project?

In the future, I envision this project contributing to advancements in geotechnical engineering practices. By refining our understanding of how gradation influences permeability, we can develop more accurate models and predictive tools for designing geotechnical structures. This knowledge can also inform strategies for sustainable land use and environmental management, ensuring that construction activities minimize their impact on natural resources. Ultimately, I hope this research will lead to safer, more efficient, and environmentally friendly engineering solutions in the field of geotechnics.
