In Situ Frost-Heaving Characteristics of Shallow Layer of Soil Slopes in Intermittently Frozen Region Based on PFC^3D

Table 6

Average along surface displacements of slopes at various frozen depths (unit: mm).

Layer of slope surface	45°	60°
First (10%)	0.138	0.164
Second (10%–20%)	0.075	0.093
Third (20%–40%)	0.039	0.072
