Preview Questions Geotechnical Engineer | Role Specific Skill

Question 1: In what scenario would a direct shear test be preferred over a triaxial shear test?

Which action should you take?

Choose only one option

When testing for shear strength at the interface of two materials under a confined load

When precise measurement of soil strength under multi-axial stress is required

When soil consolidation is a critical factor in the design

When measuring the compressive strength of soil under dynamic load

Question 2: Why is the particle size distribution important in soil classification, and how is it typically measured?

Which action should you take?

Choose only one option

It identifies the chemical composition of the soil, measured by spectrometry

It identifies the soil's thermal conductivity, measured by heat transfer techniques

It helps determine the soil's texture, which affects its compaction and permeability, and is measured through sieve analysis

It determines the soil's organic content, which influences soil fertility, measured by the combustion method

Question 3: How does the depth of soil layers affect the earthquake-induced settlement on a construction site?

Which action should you take?

Choose only one option

Deeper layers may lead to more significant settlement during seismic events

Shallow soils cause higher shear strength

Soil depth does not significantly affect earthquake settlement

Deeper soils result in less movement under seismic conditions

Question 4: How does the rate of consolidation impact the risk of long-term ground instability in foundation design?

Which action should you take?

Choose only one option

A slower rate of consolidation leads to more gradual settlement, which needs to be accounted for in design

A faster rate of consolidation increases the risk of sudden failure

The rate of consolidation only affects the aesthetic design of the foundation

The rate of consolidation has no impact on the foundation's stability

Question 5: How can fault line proximity influence foundation design in earthquake-prone regions?

Which action should you take?

Choose only one option

Fault lines are ignored in foundation design since they rarely cause issues

Proximity to fault lines requires special foundation designs to withstand ground motion and displacement

Fault lines are only a concern for tall structures and not for residential buildings

Proximity to fault lines has no significant impact on foundation design

Question 6: How is a site's susceptibility to earthquake-induced ground failure evaluated?

Which action should you take?

Choose only one option

By analyzing the soil type, depth to bedrock, and groundwater conditions

By focusing solely on the depth of the soil for construction purposes

By measuring the visual impact of past earthquakes on surrounding areas

By estimating the economic losses due to potential ground failure
