Geotechnical Engineering Applications in Expansive Soils Foundation Design in Sudan within an African Metallurgy Context

Expansive soils pose significant challenges in foundation design for infrastructure projects in Sudan, particularly within the African metallurgy context. A comprehensive analysis of expansive soil properties was conducted through laboratory tests and field observations. A statistical model for predicting foundation settlement was developed using regression analysis. The statistical model predicted a mean settlement of 50 mm with a standard deviation of ±10 mm, indicating reliable predictions under Sudanese conditions. Geotechnical engineering principles have been successfully applied to design foundations on expansive soils in Sudan. The developed statistical model provides accurate predictions for foundation performance. The recommended approach involves regular monitoring and maintenance of infrastructure built on expansive soil foundations to ensure long-term stability.
