Purpose of Site Investigation

Why is it important to conduct geotechnical investigation before construction?

• To test the color of the soil

• To practice digging holes

• To see if animals live underground

• To understand soil and rock conditions, design foundations, ensure stability, and prevent hazards.

Discuss the importance of groundwater analysis in geotechnical investigation.

• Groundwater analysis is important in geotechnical investigation to determine water table levels, soil permeability, contamination risks, and overall site stability for designing foundations and ensuring structural durability.

• Groundwater analysis is irrelevant in geotechnical investigation

• Groundwater analysis has no impact on foundation design

• Groundwater analysis only focuses on soil color

What are the key components of a geotechnical investigation report?

• Field exploration data, design drawings, cost estimates

• Recommendations, analysis and interpretations, field exploration data

• Laboratory testing results, site information, conclusions

• Site information, field exploration data, laboratory testing results, analysis and interpretations, recommendations, conclusions

Explain the significance of soil testing in geotechnical investigation.

• Soil testing is not necessary in geotechnical investigation

• Soil testing provides essential data on soil properties necessary for designing safe and stable structures.

• Soil testing does not impact the safety and stability of structures

• Soil testing only provides irrelevant data for designing structures

What is the main purpose of geotechnical investigation?

• To assess soil and rock conditions for construction projects

• To bake cookies

• To predict the weather

• To study marine life

How does geotechnical investigation help in assessing slope stability?

• Geotechnical investigation helps in assessing slope stability by counting the number of trees on the slope

• Geotechnical investigation helps in assessing slope stability by analyzing soil and rock properties, identifying potential risks of slope failure, and determining appropriate stabilization measures.

• Geotechnical investigation helps in assessing slope stability by predicting weather patterns

• Geotechnical investigation helps in assessing slope stability by measuring the distance to the nearest river

How does geotechnical investigation help in determining foundation design?

• Geotechnical investigation provides information about the weather conditions affecting the foundation

• Geotechnical investigation provides information about soil conditions, helping engineers select the right foundation type, depth, and design parameters for stability and safety.

• Geotechnical investigation helps in selecting the roof design

• Geotechnical investigation determines the color of the foundation

What are the different methods used in geotechnical investigation?

• core sampling, ground penetrating radar, soil resistivity testing

• test pits, boreholes, geophysical methods, laboratory testing

• excavation, seismic surveys, field mapping

• drilling, aerial photography, remote sensing

What role does geophysical survey play in geotechnical investigation?

• Geophysical survey involves only surface-level data collection.

• Geophysical survey is not relevant to geotechnical investigation.

• Geophysical survey provides valuable subsurface information without excavation.

• Geophysical survey is primarily used for weather forecasting.

What are the potential risks of neglecting geotechnical investigation in construction projects?

• Reduced environmental impact

• Increased project efficiency

• The potential risks of neglecting geotechnical investigation in construction projects include unforeseen ground conditions, potential foundation failures, safety hazards, cost overruns, project delays, and legal liabilities.

• Enhanced structural stability
