3. Geotechnical Applications

4. firm ground bed rock Shallow Foundations ~ for transferring building loads to underlying ground ~ mostly for firm soils or light loads

5. Shallow Foundations

6. weak soil bed rock Deep Foundations ~ for transferring building loads to underlying ground ~ mostly for weak soils or heavy loads P I L E

7. Driven timber piles, Pacific Highway Deep Foundations

8. Road Train retaining wall Retaining Walls ~ for retaining soils from spreading laterally

9. reservoir clay core shell soil Earth Dams ~ for impounding water

11. Concrete Dams Three Gorges Dam, Hong Kong

12. Concrete Dams

13. Earthworks ~ preparing the ground prior to construction Roadwork, Pacific Highway

14. Construction hazard ~ an unwelcome visitor at an earthwork site. What does it have to do with Geo?#! A dead Anaconda python (courtesy: J. Brunskill)

15. Geofabrics used on Pacific Highway Geofabrics ~ used for reinforcement, separation, filtration and drainage in roads, retaining walls, embankments…

16. Reinforced Earth Walls ~ using geofabrics to strengthen the soil

17. Soil Nailing ~ steel rods placed into holes drilled into the walls and grouted

18. warehouse ship sheet pile Sheet Piles ~ sheets of interlockingsteel or timber driven into the ground, forming a continuous sheet

19. Sheet Piles ~ resist lateral earth pressures ~ used in excavations, waterfront structures, ..

20. Sheet Piles ~ used in temporary works

21. Sheet Piles ~ interlocking sections

22. Cofferdam ~ sheet pile walls enclosing an area, to prevent water seeping in

23. Landslides

24. Shoring propping and supporting the exposed walls to resist lateral earth pressures

25. Tunneling

26. Blasting For ore recovery in mines
