Question

The best method for compaction of cohesion-less soils is

• A. Consolidation
• B. Vibration
• C. Process
• D. Deterioration

Hint:

Compaction methods: \[ \boxed{ \begin{aligned} \text{Cohesion-less soils} &\rightarrow \text{Vibration} \text{Cohesive soils} &\rightarrow \text{Kneading / Impact} \end{aligned} } \]

Answer 1

The Correct Option is B

Step 1: Recall the compaction methods. Cohesion-less soils such as sand and gravel achieve maximum density when subjected to vibration.

Step 2: Identify the suitable method. Vibratory rollers and vibrating plates are commonly used for compacting cohesion-less soils. Hence, \[ \boxed{\text{Vibration}} \] is the correct answer. Therefore, \[ \boxed{(B)} \] is the correct answer.
