Q. In the Terzaghi bearing capacity equation, what does the term 'c' represent?

Solution

In the Terzaghi bearing capacity equation, 'c' represents the cohesion of the soil, which contributes to the bearing capacity.

Correct Answer: B — Cohesion of the soil

Q. What is the primary method used to determine the bearing capacity of soil in the field?

Solution

All of the listed methods (SPT, CPT, and Plate Load Test) are commonly used to determine the bearing capacity of soil in the field.

Correct Answer: D — All of the above

Q. What is the purpose of a geotechnical site investigation?

Solution

The primary purpose of a geotechnical site investigation is to determine soil properties and conditions for safe and effective foundation design.

Correct Answer: A — To determine soil properties and conditions

Q. What is the term for the ratio of the shear strength of soil to its normal stress?

Solution

The ratio of the shear strength of soil to its normal stress is known as the friction angle, which is a critical parameter in soil mechanics.

Correct Answer: B — Friction angle

Q. Which factor does NOT affect the bearing capacity of soil?

Solution

The color of the soil does not affect its bearing capacity; factors like soil type, water table level, and foundation shape are critical.

Correct Answer: D — Color of the soil

Q. Which of the following is a method to improve the bearing capacity of weak soils?

Solution

Soil compaction is a common method used to improve the bearing capacity of weak soils by increasing their density.

Correct Answer: A — Soil compaction

Q. Which type of foundation is most suitable for high bearing capacity requirements?

Solution

Deep foundations are most suitable for high bearing capacity requirements as they transfer loads to deeper, more stable soil layers.

Correct Answer: B — Deep foundation
