Preview Questions Geotechnical Engineer | Role Specific Skill

Question 1: How does the risk of settlement influence the choice of foundation type in areas with soft, compressible soils?

Which action should you take?

Choose only one option

It makes shallow foundations more suitable

It may necessitate deep foundations or soil stabilization to control settlement

It reduces the cost of foundation materials

It is of no concern if the soil is compacted before construction

Question 2: Which of the following soil tests is most commonly used to determine the bearing capacity of the soil in construction projects?

Which action should you take?

Choose only one option

Atterberg limits

Standard Penetration Test (SPT)

Moisture content test

Direct shear test

Question 3: How does a geotechnical engineer evaluate the presence of voids or cavities in the subsurface during site analysis?

Which action should you take?

Choose only one option

By reducing the depth of excavation to minimize void-related risks

By using geophysical methods such as ground-penetrating radar (GPR) or electrical resistivity tomography to detect voids

By visual inspection and minor drilling

By assuming voids are insignificant and proceeding with standard design

Question 4: Why is a site-specific risk assessment necessary for assessing soil liquefaction potential?

Which action should you take?

Choose only one option

It estimates the amount of water in the soil

It helps estimate the aesthetic impact of soil liquefaction

It helps determine whether soil conditions under seismic loading could cause liquefaction and compromise foundation stability

It provides insights into soil temperature fluctuations during construction

Question 5: Which soil property is most critical when designing a deep foundation in unconsolidated soils to ensure ground stability?

Which action should you take?

Choose only one option

Shear strength and friction angle

Permeability and consolidation rate

Cohesion and moisture content

Plasticity index

Question 6: What is the impact of loading rate on ground stability in soft clayey soils?

Which action should you take?

Choose only one option

Faster loading increases soil compaction

Slower loading leads to greater stability

Faster loading leads to greater settlement and less stability

Loading rate does not affect stability in clayey soils
