Geotechnical Tests and Properties Matching Solution
This question requires matching specific geotechnical tests with the soil properties or analyses they determine. Let's break down each item:
Proctor Test - Compaction
The Proctor test is fundamental for determining the **compaction** characteristics of a soil, specifically its optimum moisture content and maximum dry density.
Therefore, A matches with IV.
Vane Test - Shear Strength
The Vane Shear Test is designed to measure the in-situ undrained **shear strength** of soft to medium stiff cohesive soils.
Therefore, B matches with II.
Penetration Test - Bearing Capacity
Various penetration tests, such as the Standard Penetration Test (SPT) or Cone Penetration Test (CPT), provide indices that help estimate soil strength and are correlated with **bearing capacity**.
Therefore, C matches with III.
Hydrometer Test - Grain Size Analysis
The Hydrometer test is a key method used in **grain size analysis** to determine the distribution of particle sizes, especially for fine soils like silt and clay.
Therefore, D matches with I.
Correct Match Summary
Based on the analysis, the correct pairings are:
- A - IV (Proctor test - Compaction)
- B - II (Vane test - Shear strength)
- C - III (Penetration test - Bearing capacity)
- D - I (Hydrometer test - Grain size analysis)
This corresponds to the option A-IV, B-II, C-III, D-I.
