Slope Stability Calculator

Slope geometry

Height (m) Define by Length (m)

Water table

Depth from top of slope (m) leave blank for none

Geological layers (materials)

Soil name	Layer thickness (m)	Unit weight (kN/m³)	Friction angle (°)	Effective cohesion c′ (kPa)	Color

Uniform distributed loads (UDL)

Magnitude (kPa)	Offset from crest (m)	Length (m, blank = ∞)

Line loads

Magnitude (kN/m)	Offset from crest (m)

Distributed face loads

Vertical downward. Position and length are measured along the inclined face from the crest toward the toe. Magnitude is per inclined area, not horizontal area. Select Full slope face to cover crest to toe automatically.

Magnitude (kPa / face area)	Position along face (m)	Length along face (m)	Full slope face

Face line loads

Vertical downward. Position is measured along the inclined face from the crest toward the toe.

Magnitude (kN/m)	Position along face (m)
