Preview Questions Geotechnical Engineer | Role Specific Skill

Question 1: What does the compaction characteristic curve indicate about soil in geotechnical testing?

Which action should you take?

Choose only one option

It helps assess the shear strength of the soil

It shows the relationship between plasticity and moisture content

It measures the soil's permeability under different moisture conditions

It shows the relationship between moisture content and dry density, indicating the optimal compaction conditions

Question 2: What is the primary purpose of performing a liquid limit test on soil?

Which action should you take?

Choose only one option

To assess the shear strength of the soil under moisture conditions

To assess the compaction characteristics of the soil

To determine the moisture content at which soil transitions from a plastic to a liquid state

To evaluate the permeability of the soil under different moisture levels

Question 3: How do seismic forces impact ground stability in foundation design, and how are these risks assessed?

Which action should you take?

Choose only one option

Seismic forces require more aesthetic considerations in design than structural

Seismic forces have minimal impact on ground stability in most soil types

Seismic forces require soil testing to assess soil strength and potential for liquefaction or settlement

Seismic forces are irrelevant unless the building is over 10 stories tall

Question 4: What is the primary purpose of performing a Triaxial Shear Test on soil?

Which action should you take?

Choose only one option

To measure the moisture content of the soil

To evaluate soil's compaction properties

To determine the soil's shear strength under controlled stress conditions

To analyze the permeability of the soil

Question 5: What is the main consideration when designing a foundation on sloping terrain?

Which action should you take?

Choose only one option

Stability of the slope and erosion control

Site preparation for construction access

Load distribution and foundation depth

Soil compaction and drainage management

Question 6: How does groundwater level fluctuation impact geotechnical risk assessment in foundation design?

Which action should you take?

Choose only one option

It has no significant impact on soil behavior

It increases foundation bearing capacity

It reduces liquefaction potential

It influences soil settlement and shear strength
