## Question

Write the scope of engineering geology in the field of civil engineering.

## Short answer

Engineering geology applies geological knowledge to civil engineering works. Its scope includes site investigation, foundation studies, slope stability, tunnelling, groundwater, construction materials, hazard assessment, and geological mapping to ensure safety, economy, and environmental protection.

## Answer

**Engineering geology** applies geological knowledge to the investigation, design, construction and maintenance of civil engineering works. Its scope in civil engineering includes:

1. **Site selection and investigation** for dams, reservoirs, tunnels, bridges, roads, canals and buildings.
2. **Foundation studies:** bearing capacity, weak zones, faults, weathering and settlement.
3. **Slope stability and landslide study** for road cuts, dam abutments and reservoir rims.
4. **Tunnelling and underground works:** rock mass classification, support design, water inflow, squeezing and rock burst.
5. **Groundwater studies:** seepage, dewatering, water supply and drainage.
6. **Construction materials:** locating and testing aggregates, sand, clay, building stones.
7. **Geological hazards:** earthquake, flood, GLOF, erosion, subsidence, with mitigation.
8. **Geological mapping and rock/soil testing** for design parameters.
9. **Environmental and cost aspects:** helps avoid failures, environmental damage, cost overruns and delays.
