This document discusses deep foundations such as pile foundations. It introduces pile foundations as an alternative to shallow foundations for structures where the soil conditions pose risks of bearing capacity failure or excessive settlement. Pile foundations are classified and examples are provided of different pile foundation applications. The document also notes that while pile driving formulas exist, they do not always provide accurate predictions of pile capacity due to variable soil resistance during and after pile installation.
Chapter 4 (deep foundation)
- 2. Introduction • Shallow foundation sometime subjected to bearing capacity failure and/or excessive settlement. • The failure resulted by poor condition of existing soil. • In such cases, deep or pile foundations may be used to support the structure.
- 3. Situation of Considering Pile Foundation
- 4. Classifications of Pile Foundation
- 12. Example 1
- 15. Example 2
- 21. Example 3
- 23. Example 4
- 26. Example 5
- 28. Pile Driving Formula • Generally, no pile driving formula has been developed that gives accurate results for pile capacity • Soil resistance does not remain constant during and after the pile driving operation • Pile driving
