Preview Questions Geotechnical Engineer | Role Specific Skill

Question 1: In site analysis, which soil property is most critical for predicting long-term settlement of foundations in soft clay?

Which action should you take?

Choose only one option

Moisture content and plasticity index

Shear strength and friction angle

Permeability and bearing capacity

Coefficient of consolidation (Cv)

Question 2: How does a geotechnical engineer assess the risk of settlement in areas with weak or compressible soils during site analysis?

Which action should you take?

Choose only one option

By conducting soil consolidation and shear strength tests to determine compressibility and bearing capacity

By measuring the water table depth and estimating settlement rates

By focusing on the aesthetic impact of settlement on the site

By reducing the depth of the foundation to avoid settlement

Question 3: How does a soil's moisture content affect its shear strength during soil testing?

Which action should you take?

Choose only one option

Increased moisture content increases the bearing capacity of soil

Moisture content has no effect on shear strength

Increased moisture content generally decreases shear strength, especially in fine-grained soils

Increased moisture content increases the shear strength of the soil

Question 4: How does the type of soil affect the selection of foundation type for a construction project?

Which action should you take?

Choose only one option

The type of soil only affects the excavation method

Soil type primarily affects the aesthetic design of the foundation

The soil type does not significantly impact the foundation choice

Different soil types have varying load-bearing capacities, which influence the choice of shallow or deep foundations

Question 5: What is the significance of performing a cone penetration test (CPT) during foundation design?

Which action should you take?

Choose only one option

It provides detailed information about soil stratigraphy and strength for foundation analysis

It provides a basic overview of the soil's texture

It measures the moisture content of the soil

It estimates the settlement of the foundation

Question 6: What is the role of ground improvement techniques (e.g., grouting, soil stabilization) in enhancing ground stability?

Which action should you take?

Choose only one option

Ground improvement techniques only affect the aesthetic quality of the ground

Ground improvement techniques enhance the load-bearing capacity of weak soils, reducing settlement risks and improving stability

Ground improvement techniques reduce the shear strength of soil

These techniques make the ground more porous, improving stability
