Geotechnical Profiling Using Dynamic Cone Penetration Test:a Case Study of Ugiole -Aviele,edo State ,nigeria.

Geotechnical profiling is crucial in understanding subsurface conditions for civil engineering projects. This thesis presents a comprehensive study on the application of the Dynamic Cone Penetration Test (DCPT) in geotechnical profiling at Ugiole-Aviele, Edo State, Nigeria. The study aims to determine the soil's engineering properties, analyze the subsurface stratigraphy, and evaluate the suitability of the site for construction purposes. Through detailed fieldwork and data analysis, this research provides insights into the soil characteristics of the region, offering valuable information for future infrastructure development. Understanding subsurface conditions is essential for the safe and efficient design of foundations, roads, and other infrastructure. Geotechnical profiling involves systematic investigation and assessment of soil and rock properties, which directly influence the behavior and performance of structures. DCPT is a widely used field test in geotechnical engineering due to its simplicity, cost- effectiveness, and ability to provide immediate results. It involves driving a metal cone into the ground using a standard weight and hammer, recording the number of blows required to penetrate each unit of depth. These measurements reflect the soil's resistance and can be correlated with various engineering properties.The study conducted at Ugiole-Aviele involves extensive fieldwork where DCPT is employed to collect data on soil resistance at different depths. This data is then analyzed to interpret the subsurface stratigraphy, which is the layering of different soil types and their respective properties. By understanding the stratigraphy, engineers can identify potential challenges such as weak soil layers, water tables, and other geotechnical hazards that might impact construction. Additionally, the research evaluates the engineering properties of the soil, such as strength, density, and bearing capacity, which are critical for determining the suitability of the site for various construction purposes. The findings from this study are intended to guide infrastructure development in Ugiole-Aviele, providing a scientific basis for decision-making in civil engineering projects. This ensures that structures built on the site will be safe, durable, and cost-effective, minimizing the risk of structural failure and optimizing construction practices. By presenting detailed fieldwork and data analysis, this research contributes valuable knowledge to the field of geotechnical engineering, particularly in the context of Ugiole-Aviele. It serves as a reference for future studies and construction projects in the region, highlighting the importance of thorough geotechnical profiling in ensuring successful infrastructure development.
