DESIGN METHODOLOGY FOR PILES |
| |
The detailed design methodology of piles is described in the following sections. |
| |
REQUIREMENT FOR DEEP FOUNDATIONS |
| |
Generally for structures with load >10  , we go for deep foundations. Deep foundations are used in the following cases: |
 |
Huge vertical load with respect to soil capacity. |
|
Very weak soil or problematic soil. |
|
Huge lateral loads eg. Tower, chimneys. |
|
Scour depth criteria. |
|
For fills having very large depth. |
|
Uplift situations (expansive zones) |
|
Urban areas for future large and huge construction near the existing building. |
| |
CLASSIFICATION OF PILES |
| 1. |
Based on material |
|
Timber piles |
|
Steel piles |
|
Concrete piles |
|
Composite piles (steel + concrete) |
| 2. |
Based on method of installation |
|
Driven piles ----(i) precast (ii) cast-in-situ. |
|
Bored piles. |
| 3. |
Based on the degree of disturbance |
|
Large displacement piles (occurs for driven piles) |
|
Small displacement piles (occurs for bored piles) |
