Preview Questions Geotechnical Engineer | Role Specific Skill

Question 1: Why is it essential to assess the groundwater conditions during site analysis?

Which action should you take?

Choose only one option

Groundwater conditions only affect landscaping design

Groundwater conditions influence only surface drainage systems

Groundwater conditions have no significant effect on site stability

Groundwater conditions affect soil strength, foundation design, and the risk of soil liquefaction during construction

Question 2: What factors are crucial when determining the need for a deep foundation in an earthquake-prone area?

Which action should you take?

Choose only one option

Soil strength, groundwater conditions, and seismic activity

The height of the building and the cost of materials

The proximity to urban areas and transportation routes

The availability of labor and construction equipment

Question 3: In the design of underpinning foundations, which method is commonly used when strengthening existing foundations?

Which action should you take?

Choose only one option

Helical piling

Steel piers

Bored piling

Concrete underpinning

Question 4: What is the effect of an earthquake on shallow foundations when constructed on loose or unconsolidated soils?

Which action should you take?

Choose only one option

Increased friction and stability

Minimal effects due to low seismic wave propagation

No effects if deep foundations are used

Increased liquefaction and settlement

Question 5: In soil testing, what is the role of the Atterberg limits and how are they used for geotechnical analysis?

Which action should you take?

Choose only one option

They define the plasticity of fine-grained soils, which influences their suitability for different foundation types

They are used to assess the rate of consolidation in cohesive soils

They measure the permeability of coarse-grained soils

They help determine the organic content of the soil

Question 6: How can the presence of deep soils with low bearing capacity affect the risk assessment of a foundation design?

Which action should you take?

Choose only one option

It increases the risk of liquefaction under seismic conditions

It has no impact on foundation design unless the soil is saturated

It increases the risk of excessive settlement, requiring special foundation designs

It decreases the risk of soil movement and provides better stability
