Table 7
The increment of Pult at the depth of 3 m.
| | Model type | Ultimate soil reaction force | Improvement | | Pult/MN (m) | (%) |
| | The single pile foundation (d = 6 m) | 1.20 | — | | The pile-bucket foundation (D = 18 m and H = 12 m) | 4.27 | 255.83 | | The pile-bucket foundation (D = 24 m and H = 6 m) | 6.07 | 405.83 | | The pile-bucket foundation (D = 24 m and H = 12 m) | 6.26 | 421.67 | | The pile-bucket foundation (D = 24 m and H = 18 m) | 5.81 | 384.17 | | The pile-bucket foundation (D = 30 m and H = 12 m) | 8.14 | 578.33 |
