Soil and Foundation Engineering Questions

Multiple choice

A geotechnical engineer is working on a project that is located in a karst area. The engineer knows that the design of the project must take into account the potential for karst collapse. However, the client is unwilling to pay for the additional costs associated with karst collapse-resistant design. The engineer should:

  1. Design the project without taking into account the potential for karst collapse

  2. Talk to the client about the risks of not taking into account the potential for karst collapse

  3. Refuse to design the project if the client is unwilling to pay for karst collapse-resistant design

  4. Quit the project

  1. Z-shaped sheet piles

  2. U-shaped sheet piles

  3. Anchored sheet piles

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

Anchored sheet piles are commonly used for deep excavations in soft soil conditions due to their ability to resist high lateral loads.

Multiple choice

What is the term used to describe the ability of a soil to resist deformation under load?

  1. Shear strength

  2. Compressibility

  3. Permeability

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

Shear strength is the ability of a soil to resist deformation under shear stress, which is the stress that causes one part of a soil mass to slide past another.

Multiple choice

Which soil property is primarily responsible for the soil's ability to drain water?

  1. Cohesion

  2. Friction angle

  3. Permeability

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

Permeability is the ability of a soil to allow water to flow through it. It depends on the size and interconnectedness of the soil pores.

Multiple choice

What is the term used to describe the pressure exerted by soil on a structure?

  1. Lateral earth pressure

  2. Hydrostatic pressure

  3. Overburden pressure

  4. Pore water pressure
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
