Back-analysed rock mass stiffness
| Description | Relationship | When to use |
|---|---|---|
| Robust lower bound | E LB = 430 × UCS | This relationship is proven and robust and may be used as default on Dubai projects. |
| Upper bound | E UB = 1720 × UCS | Before implementation, this relationship should be proven through pile testing. This may be done through PTP(s) loaded to geotechnical failure or through working pile load tests. |
