Simple liquefaction ‘Can-test’ could help prevent the the risk

The Standard Penetration Test (SPT) is a widely used in-situ geotechnical field test that evaluates the engineering properties of subsurface soils for foundation design. It involves driving a specialized sampler into the ground using a standardized hammer and recording the number of blows. Purpose and Applications The primary goal of the SPT is to determine the soil's resistance to penetration, known as the "N-value". This value and the collected soil samples provide engineers with crucial data
