Table 5
Percentage increment of maximum circumferential strain value for pipes with different nominal diameters under various backfill conditions.
| Loose area | Inside diameter (mm) | Crest (%) | Valley (%) | Liner (%) | The maximum difference between the valley and liner (%) |
| Left side of Layer 02 | 400 | 59 | 23 | 26 | 16 | 800 | 25 | 28 | 34 | 27 | Left side of Layer 03 | 400 | 60 | 20 | 27 | 14 | 800 | 18 | 26 | 33 | 27 | Left of Layer 02 and right of Layer 03 | 400 | 77 | 40 | 44 | 32 | 800 | 32 | 39 | 48 | 36 |
