584 Questions

Soil and foundation engineering questions address the physical and mechanical properties of soil critical for construction and stability. The topics include shear strength, soil compaction, void ratios, and subsurface investigation techniques. These advanced geotechnical concepts are typically evaluated in civil engineering and specialized recruitment examinations.

Soil and Foundation Engineering Questions

Multiple choice

Water is hold by soil which is called _________.

  1. Soil profile

  2. Percolation rate

  3. Soil moisture

  4. Soil capacity
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Soil moisture is the term for water held in soil. This water is available for plant uptake and exists in the pore spaces between soil particles. Soil profile refers to soil layers, percolation rate is drainage speed, and soil capacity is not a standard term.

Multiple choice

Match the following:

 
a. Capillary water 1. It is the water that forms an extremely thin, tightly held film around the soil particles.
b. Hygroscopic water 2. It is the small portion of soil water that is chemically bound with soil materials.
c. Combined water 3. It is the water that moves against the pull of gravity when tiny pore spaces in the soil act as capillaries.

  1. a - 3, b - 1, c - 2

  2. a - 3, b - 2, c - 1

  3. a - 1, b - 3, c - 2

  4. a - 1, b - 2, c - 3

  5. a - 2, b - 1, c - 3

A Correct answer
Explanation

This is the correct option. Capillary water is the water that moves against the pull of gravity when tiny pore spaces in the soil act as capillaries. Hygroscopic water is the water that forms an extremely thin, tightly held film around the soil particles. Combined water is the small portion of soil water that is chemically bound with soil materials.

Multiple choice

What is measured in cubic meter?

  1. Rain

  2. Weight

  3. Area

  4. Volume

D Correct answer
Explanation

Cubic meter is the SI unit of volume. It represents the space occupied by a cube with edges of one meter length.

Multiple choice

A good bonding in bricks which are uniform in size

  1. All bricks should not be of same size

  2. Bricks should be soaked in water for more than 24 hours before use.

  3. The vertical joints in alternate course should fall in plumb

  4. Cement mortar must have surkhi as additive

  5. The use of brick bats should be used in alternate course

C Correct answer
Explanation

Vertical joints in alternate layers should be vertically above each other

Multiple choice

Two series of compaction tests were performed in the laboratory on an inorganic clayey soil employing two different levels of compaction energy per unit volume of soil. With regard to above tests, the following two statements are made. I. The optimum moisture content is expected to be more for the tests with higher energy. II. The maximum dry density is expected to be more for the tests with higher energy. The CORRECT option evaluating the above statements is

  1. Only I is true

  2. Only II is true

  3. Both I and II are true

  4. Neither I or II is true

B Correct answer
Multiple choice

The embankment is to be constructed with a granular soil (bulk unit weight = 20 kN/m3) on a saturated clayey slit deposit (undrained shear strength = 25 k Pa). Assuming undrained general shear failure and bearing capacity factor of 5.7 the maximum height (in m) of the embankment at the point of failure is

  1. 7.1

  2. 5.0

  3. 4.5

  4. 2.5
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

For undrained general shear failure of an embankment on soft clay, the bearing capacity is calculated using the formula H = (c * Nc) / gamma, where Nc is the bearing capacity factor. Using H = (25 * 5.7) / 20 = 7.125 m.
