Preview Questions Geotechnical Engineer | Role Specific Skill

Question 1: In geotechnical risk assessment, what is the most common method for estimating settlement in cohesive soils?

Which action should you take?

Choose only one option

Consolidation testing

Plasticity index test

Standard Penetration Test (SPT)

Triaxial shear test

Question 2: What is the significance of conducting a hydrogeological study for large construction projects?

Which action should you take?

Choose only one option

It estimates the aesthetic appearance of the groundwater near the site

It assesses the volume of water required for the construction process

It predicts the total cost of groundwater removal

It provides crucial data on groundwater flow, quality, and potential risks, guiding design decisions

Question 3: What is the significance of conducting a groundwater risk assessment in flood-prone areas?

Which action should you take?

Choose only one option

It determines the effect of water temperature on foundation materials

It only evaluates the groundwater content for landscaping purposes

It helps determine potential groundwater movement and flooding risks that could affect foundation stability and integrity

It helps estimate the aesthetic appearance of the site during flood events

Question 4: What is the effect of a high groundwater table on the stability of shallow foundations?

Which action should you take?

Choose only one option

It improves the cohesion and shear strength of the soil

It can lead to soil instability, erosion, and excessive settlement, requiring deep foundations or dewatering

It has minimal effect as long as proper drainage is in place

It stabilizes the soil by increasing its bearing capacity

Question 5: What is the key consideration when designing a deep foundation for a structure in soft clay soil?

Which action should you take?

Choose only one option

The proximity to groundwater and drainage systems

The settlement characteristics of the soil and the load distribution

The aesthetic appeal of the foundation

The material costs of foundation construction

Question 6: During an earthquake impact study, how does soil liquefaction affect the structural stability of foundations?

Which action should you take?

Choose only one option

Loss of foundation support due to soil displacement

Increased load-bearing capacity

No significant effect if deep foundations are used

Increased friction between the foundation and soil
