Design parameters of ground improvement techniques
| Ground improvement techniques | Mass of cement slurry: % | Water–cement (w/c) ratio | 28 d unconfined compressive strength: MPa |
|---|---|---|---|
| Deep soil mixing (dual-auger) | 13 | 0·45–0·6 | ≥0·6 |
| Deep soil mixing (triple-auger) | 20 | 1·5–2·0 | ≥0·8 |
| Jet grouting | 25 | 0·8–1·5 | ≥1·0 |
