In a study on the settlement of piles used in building foundations, data on the observed pile settlement were collected and compared with the calculated/estimated values. The ratio of the observed to the calculated settlements is a measure of the accuracy of the calculation method. The ratios are shown in the table below and as can be observed, it shows considerable variability:
Ratios of Observed Settlement to Calculated Settlement of Piles
0.12 | 0.97 | 0.86 | 1.14 | 0.94 |
2.37 | 0.88 | 0.92 | 1.01 | 0.99 |
1.02 | 1.04 | 0.99 | 0.87 | 0.52 |
0.94 | 1.06 | 1.38 | 1.04 | 1.18 |
1 | 0.86 | 0.82 | 0.84 | 1.09 |
