Preview Questions Geotechnical Engineer | Role Specific Skill

Question 1: When conducting a site analysis for a high-rise building, which factor most affects differential settlement between varied soil layers?

Which action should you take?

Choose only one option

Moisture content and plasticity index

Soil compressibility and foundation depth

Shear strength and load distribution

Soil permeability and density

Question 2: What is the primary cause of ground instability during rapid excavation in highly saturated soils?

Which action should you take?

Choose only one option

Low shear strength causing lateral displacement

High hydrostatic pressure leading to soil instability

Plasticity index leading to slump failure

Increased permeability causing increased groundwater flow

Question 3: What is the primary challenge when conducting a site analysis on expansive soils for shallow foundations?

Which action should you take?

Choose only one option

Swelling and shrinking due to moisture fluctuation

High permeability causing increased drainage

Low shear strength and settlement potential

Increased plasticity leading to poor compaction

Question 4: In the context of groundwater management, what does the term "cone of depression" refer to?

Which action should you take?

Choose only one option

The increase in water table after a significant rainfall

The distribution of contaminants in the aquifer

The reduction in groundwater level around the pumping well

The shift in water flow due to barriers

Question 5: What is the impact of high groundwater levels on the excavation of deep foundations, and how are these risks managed?

Which action should you take?

Choose only one option

High groundwater levels reduce the load on deep foundations

High groundwater levels cause minimal impact on foundation excavation

High groundwater levels improve foundation stability

High groundwater levels increase the risk of flooding and soil instability, requiring dewatering systems and stable shoring

Question 6: How does the permeability of the underlying soil affect the design of a groundwater control system for a deep excavation?

Which action should you take?

Choose only one option

High permeability increases the difficulty of controlling groundwater and may require more powerful dewatering systems

Low permeability makes groundwater management unnecessary

Permeability does not influence the design of the dewatering system

Permeability influences only the type of foundation to be used
