Genstru Consultants Geotechnical Engineer Interview Questions, Process, and Tips

Liquefaction is a phenomenon where soil loses its strength and stiffness due to increased pore water pressure.

• Occurs during earthquakes or other vibrations

• Can cause soil to behave like a liquid

• Can lead to soil settlement, landslides, and building damage

• Common in areas with loose, sandy soil

Retaining walls are structures used to hold back soil or rock. There are several types of retaining walls.

• Gravity retaining walls

• Cantilever retaining walls

• Sheet pile retaining walls

• Anchored retaining walls

• Gabion retaining walls

• Reinforced soil retaining walls

Geosynthetics are materials used in geotechnical engineering to improve soil stability and performance.

• Geotextiles: used for soil separation, filtration, and drainage

• Geogrids: used for soil reinforcement and stabilization

• Geomembranes: used for containment and barrier systems

• Geocomposites: combination of different geosynthetic materials

• Geocells: three-dimensional honeycomb-like structures used for erosion control and lo

Types of foundations, retention systems, and geotechnical terms.

• Types of foundations include shallow foundations (e.g. spread footings, mat foundations) and deep foundations (e.g. piles, drilled shafts).

• Retention systems refer to structures used to retain soil or other materials, such as sheet piles, soldier piles and lagging, and soil nails.

• SPT (Standard Penetration Test) is a common in-situ test to determine soil pro...read more
