Q1: Which of the following pairs are correctly matched ?
1. Standard penetration test....Relative density
2. Vane shear....Cohesion
3. Consolidation test....Bearing capacity
Select the correct answer using the codes given below :

ANS:C - 1 and 2

The Standard Penetration test (SPT) is a common in situ testing method used to determine the geotechnical engineering properties of subsurface soils. It is a simple and inexpensive test to estimate the relative density of soils and approximate shear strength parameters.

The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density.

The consolidation test is used to determine the rate and magnitude of soil consolidation when the soil is restrained laterally and loaded axially and the rate and magnitude of settlement in soils.
