Excavation Safety: Proper slope angles prevent cave-ins and ensure worker safety. Different soil types require different slope ratios based on their stability characteristics.
Slope Angles by Soil Type
Rock: 90° | Type A: 53° | Type B: 45° | Type C: 34°
Rock: 90° | Type A: 53° | Type B: 45° | Type C: 34°
Soil Classifications
Stable Rock: Vertical excavation allowed (90° slope angle).
Type A Soil: Cohesive soils with unconfined compressive strength ≥ 1.5 tsf (144 kPa).
Type B Soil: Cohesive soil 0.5-1.5 tsf strength, granular cohesionless soils.
Type C Soil: Cohesive soil ≤ 0.5 tsf, granular soils, submerged soils.
