Preview Questions Geotechnical Engineer | Role Specific Skill

Question 1: Why is it important to measure the compressibility of soil in geotechnical analysis?

Which action should you take?

Choose only one option

To determine the soil's permeability under hydraulic pressure

To assess the shear strength of the soil at various depths

To estimate potential settlement under applied loads and ensure foundation stability

To analyze the organic content of the soil for fertility concerns

Question 2: What is the primary concern when conducting site analysis for foundations in areas with high seismic risk and soft soils?

Which action should you take?

Choose only one option

Liquefaction potential and foundation stability

Moisture content and soil cohesion

Soil erosion and erosive conditions

Plasticity index and soil permeability

Question 3: How is ground stability impacted by the soil's plasticity index?

Which action should you take?

Choose only one option

A higher plasticity index weakens the soil, reducing stability

The plasticity index indicates the soil's ability to undergo deformation without cracking, influencing ground stability

The plasticity index has no effect on ground stability

Higher plasticity always leads to higher soil stability

Question 4: What is the primary advantage of a deep foundation over a shallow foundation in certain conditions?

Which action should you take?

Choose only one option

It provides support when the upper soil layers are weak or unstable

It avoids the need for soil testing at the site

It requires less excavation and minimal material use

It is less costly to install than shallow foundations

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 does the grain size distribution analysis tell us about a soil sample?

Which action should you take?

Choose only one option

It assesses the water retention capability of the soil

It calculates the soil's compaction index

It measures the amount of organic material in the soil

It helps determine the soil's suitability for certain uses, such as foundations or drainage
