Experimental factors and their level values.
| Level | Factor | Particle composition | Water content | Soil layer thickness | Crack width | Symbol | Cc | ω | Cl | Cw |
| 1 | | Cc10 (soil-sand ratio 1 : 0) | ω15 (15%) | | Cw1 (1.0 mm) | 2 | | Cc11 (soil-sand ratio 1 : 1) | ω20 (20%) | Cl10 (10.0 cm) | Cw2 (2.0 mm) | 3 | | Cc13 (soil-sand ratio 1 : 3) | ω25 (25%) | Cl15 (15.0 cm) | Cw3 (3.0 mm) |
