Table 6
The increment of Pult at the depth of 4.5 m.
| | Model type | Ultimate soil reaction force | Improvement | | Pult/MN (m) | (%) |
| | The single pile foundation (d = 6 m) | 1.52 | — | | The pile-bucket foundation (D = 18 m and H = 12 m) | 3.86 | 153.95 | | The pile-bucket foundation (D = 24 m and H = 6 m) | 3.25 | 113.82 | | The pile-bucket foundation (D = 24 m and H = 12 m) | 5.58 | 267.11 | | The pile-bucket foundation (D = 24 m and H = 18 m) | 5.05 | 232.24 | | The pile-bucket foundation (D = 30 m and H = 12 m) | 7.51 | 394.08 |
