| Features of STATIC Load Tests |
|
|
| |
Advantages |
|
| |
- Static behaviour
- Maintained load
- Cyclic loading
- No pile damage
- Direct load measurement (calibrated load cell)
- Direct displacement measurement
|
|
|
|
Disadvantages |
|
|
- Expensive
- Time consuming
- Different procedures

| Features of DYNAMIC Load Tests |
|
|
|
|
|
| |
Advantages |
|
| |
- Economic
- Quick
|
|
|
|
Disadvantages |
|
| |
- Indirect load measurements
strain transducers : F = E.A. e
concrete piles : E variable
bored piles: E and A variable
- Indirect displacement measurements accelerometers, u = ff a.dt
- Calibration to static load test
- Experienced high level educated engineers
- Chance on pile damage
- In many cases capacity not mobilised
