Granular fill friction angle
Web• There is friction between the wall and soil and takes this into account by using a soil-wall friction angle of δ. Note that δ ranges from φ/2 to 2φ/3 and δ = 2φ/3 is commonly used. • Lateral pressure is not limited to vertical walls • The resultant force is not necessarily parallel to the backfill surface because of the WebJul 12, 2024 · Springer.
