11
The compressibility of soil is quantified using:
Discuss
Answer & Solution
Answer: Option
Solution:
The Oedometer test measures one-dimensional settlement of soil under vertical load.Used to estimate consolidation and settlement in structures.
12
What is the term for the smallest size particle in soil classification?
Discuss
Answer & Solution
Answer: Option
Solution:
Clay particles are the smallest (< 0.002 mm).They exhibit high plasticity, low permeability, and large surface area.
13
Which soil improvement technique increases bearing capacity using vertical loads?
Discuss
Answer & Solution
Answer: Option
Solution:
Preloading involves placing temporary loads on soil to accelerate consolidation and reduce settlement under future loads.Common in soft clay foundations.
14
Which factor most reduces the durability of rocks?
Discuss
Answer & Solution
Answer: Option
Solution:
Fissures and joints act as zones of weakness where weathering and water ingress accelerate deterioration.This reduces the long-term performance of rocks in engineering structures.
15
What is the unit of permeability coefficient?
Discuss
Answer & Solution
Answer: Option
Solution:
The coefficient of permeability has the unit m/s and quantifies the velocity at which water flows through a soil or rock per unit hydraulic gradient.
16
What is the primary factor influencing the compaction of soil?
Discuss
Answer & Solution
Answer: Option
Solution:
Moisture content affects the ease with which soil particles can be rearranged under compactive effort.Too dry or too wet soils do not compact well. Optimal moisture is necessary for maximum dry density.
17
The angle of internal friction of a soil affects its:
Discuss
Answer & Solution
Answer: Option
Solution:
Angle of internal friction is a measure of the shear resistance due to interparticle friction.Higher angle = better strength and slope stability.
18
Which test is commonly used to determine the Atterberg limits?
Discuss
Answer & Solution
Answer: Option
Solution:
The Casagrande test determines the liquid and plastic limits of soil.These define the plasticity characteristics of fine-grained soils.
19
The resistance of a soil or rock to deformation under stress is called:
Discuss
Answer & Solution
Answer: Option
Solution:
Stiffness is the ability of a material to resist deformation under load.In soil mechanics, it is evaluated through modulus of elasticity.
20
Permeability of soil is highest in:
Discuss
Answer & Solution
Answer: Option
Solution:
Gravel has the largest particle sizes and voids.This allows water to flow through easily, resulting in very high permeability compared to other soils.
