ANSWER : (C) 1 and 2
Standard penetration Test (SPT) is for the test is to provide an indication of the relative density of granular deposits, such as sands and gravels
Vane Shear is to find shear strength of cohesive soils soil specimen.
Cone Penetration Test (CPT) is mainly determined the soil geotechnical property of bearing capacity
Consolidation Test is conducted to determine the settlement due to primary consolidation. To determine :Rate of consolidation under normal load.Degree of consolidation at any time. iii. Pressure-void ratio relationship.Coefficient of consolidation at various pressures.Compression index. From the above information it will be possible for us to predict the time rate and extent of settlement of structures founded on fine-grained soils. It is also helpful in analyzing the stress history of soil. Since the settlement analysis of the foundation depends mainly on the values determined by the test, this test is very important for foundation design.
