Multiple choice

How does the presence of expansive soils impact infrastructure development?

  1. They can cause damage to foundations and structures due to swelling and shrinking.

  2. They require special engineering techniques to mitigate their effects.

  3. They are unsuitable for construction purposes.

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Expansive soils can cause significant damage to foundations and structures due to their ability to swell and shrink with changes in moisture content. This swelling and shrinking can lead to cracks, uneven settlement, and structural instability.

Multiple choice

Multiple choice

Which of the following is NOT a common rock property measured in Rock Mechanics?

  1. Density

  2. Porosity

  3. Compressive strength

  4. Electrical resistivity
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Electrical resistivity is not typically measured in Rock Mechanics, as it is more relevant to geophysics and soil properties.

Multiple choice

What is the primary cause of rock failure in underground excavations?

  1. Shear stress

  2. Tensile stress

  3. Compressive stress

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

Shear stress, caused by the weight of the overlying rock and the geometry of the excavation, is the primary cause of rock failure in underground excavations.

Multiple choice

What is the primary factor influencing the stability of a slope?

  1. Slope angle

  2. Soil or rock properties

  3. Groundwater conditions

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
