Preview Questions Geotechnical Engineer | Role Specific Skill

Question 1: How is the liquefaction potential of soil evaluated during earthquake assessments?

Which action should you take?

Choose only one option

By measuring the amount of organic material in the soil

By assessing the soil's density, grain size, and water content to predict its behavior under seismic forces

By estimating the compressibility of the soil

By evaluating the shear strength of the soil under static conditions

Question 2: What is the significance of conducting a soil shear test when assessing ground stability in loose, granular soils?

Which action should you take?

Choose only one option

It tests the organic content of the soil for determining stability

It determines the soil's ability to resist lateral forces, essential for slope stability analysis

It helps estimate the permeability of the soil

It measures the soil's density and compaction characteristics

Question 3: How does the consolidation behavior of soil affect the long-term stability of foundations in clayey soils?

Which action should you take?

Choose only one option

Consolidation has no effect on foundation stability

Consolidation accelerates settlement, reducing the need for deep foundations

Slow consolidation can lead to excessive settlement under load, requiring deeper or more robust foundations

Consolidation leads to soil compaction, improving foundation stability

Question 4: In the context of earthquake engineering, what is the significance of soil amplification?

Which action should you take?

Choose only one option

It helps in reducing the magnitude of earthquakes

It determines how much liquefaction will occur during an earthquake

It refers to the increase in seismic wave intensity as they pass through softer soils, leading to greater ground shaking

It describes the reduction of seismic forces in soft soils

Question 5: In geotechnical site analysis, how does soil permeability influence foundation design?

Which action should you take?

Choose only one option

High permeability increases the soil's shear strength

High permeability reduces the load-bearing capacity of the soil

Soil permeability has no impact on foundation stability

High permeability can cause excessive water flow through the soil, leading to erosion or weakening of the foundation structure

Question 6: During an earthquake hazard analysis, which soil property is most critical for assessing site amplification of seismic waves?

Which action should you take?

Choose only one option

Plasticity index

Moisture content of the soil

Organic content

Soil stiffness and density
