A slope refers to a graded surface constructed on both sides of the roadbed to ensure the stability of the base.
What factors affect the stability of subgrade slopes?
1. Subgrade Slope Ratio
The gentler the roadbed slope, the better the stability of the embankment's slope.
2. Groundwater levels
Groundwater levels affect the stability of subgrade and reduce the slope stability more significantly in areas with higher water tables.
3. Quality of temporary drainage and slope protection engineering.
4. Subgrade Fill Material
The fill material for the subgrade should be chosen for its good permeability and high strength.
5. Roadbed Compaction Quality
The higher the compaction quality of the subgrade, the better the stability of the subgrade slope.
Above are the relevant matters concerning the slope, we hope they are helpful to you.
