Spt is sufficient for which soil
WebThe reason why SPT records change seasonally is the reduction of matric suction in soil. Matric suction is an apparent increase in cohesion in unsaturated soils. WebAnswer: Soil samples are to be collected up to 10 meters below ground level. Along with this standard penetration test has to be conducted to assess the soil resistance and SPT values at every 60 cm depth or whenever the soil stratum changes. This is correlated to assess the bearing capacity of s...
