Question 1: How does soil consolidation influence ground stability in areas with a high water table?

Which action should you take?

Choose only one option

Consolidation has minimal impact unless the soil is highly organic

Consolidation can cause settlement, which must be accounted for in foundation design to prevent structural failure

Consolidation reduces soil permeability, stabilizing the foundation

Consolidation accelerates the settlement process, reducing design complexity

Question 2: 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 3: What is the effect of soil compaction on the shear strength of granular soils?

Which action should you take?

Choose only one option

Compaction has no effect on the shear strength of granular soils

Compaction decreases the density and shear strength of granular soils

Compaction increases the permeability, reducing shear strength

Compaction increases the soil's density, leading to higher shear strength and stability

Question 4: How is the risk of soil liquefaction assessed during a geotechnical risk assessment?

Which action should you take?

Choose only one option

By measuring the shear strength of the soil under static conditions

By evaluating the soil's composition, density, and groundwater conditions to predict liquefaction under seismic loading

By calculating the moisture content and plasticity of the soil

By evaluating the depth of the soil layer only

Question 5: In geotechnical engineering, what is the primary goal of conducting a piezometer test in relation to ground stability?

Which action should you take?

Choose only one option

To calculate the plasticity index of the soil

To measure pore water pressure and determine soil stability

To evaluate shear strength of the soil

To measure soil permeability and flow rate

Question 6: What is the role of geotechnical site analysis in determining the risk of landslides or soil erosion for a construction site?

Which action should you take?

Choose only one option

It helps determine the project timeline based on geotechnical conditions

It helps evaluate soil cohesion, slope stability, and the effects of external factors like water or seismic activity

It only assesses the organic content of the soil

It is mainly concerned with measuring the aesthetic appeal of the site
