Field testing and soil classification are essential parts of geotechnical investigations in Bangladesh, helping engineers quickly assess ground conditions for construction projects. Common field tests include the Standard Penetration Test (SPT), Cone Penetration Test (CPT), and field density tests, which provide valuable information about soil strength, density, and consistency. Classification systems like the Unified Soil Classification System (USCS) and local adaptations are used to categorize Bangladesh’s diverse soils, ranging from soft clays to sandy deposits. Accurate field testing ensures safer designs, especially in areas prone to flooding and settlement.
