Consider the following statements: 1. Standard penetration test is commonly used for cohesionless soils. 2. Standard penetration test results in respect of a cohesionless soil are correlated to its density index and friction angle. 3. Use of H-value not corrected for overburden pressure leads to highly conservative design of footings at shallow depths. Which of these statements are correct?
2.
Consider the following statements: 1. The benefit of surcharge and depth of foundation is only marginal in case of footings on purely cohesive soils. 2. The bearing capacity of a footing in pure clay increases with increase in size of the footing. 3. Size effects in plate load tests are more important in case of cohesionless soils. Which of these statements are correct?
