Conclusion

The use of the main methods of calculating Kc in practice guarantees an accuracy of the calculation within

$$0.85K_p< K_c< K_p $$

for ℵ≤15° (the sliding wedge is separated from the slope by the surface of sliding not having an ascending branch) — the methods of Terzaghi and its analogues, Krey and its analogues, IFI; for ℵ<90° (the sliding wedge is separated from the slope by a surface of sliding having an ascending branch, on the surface of sliding the ratio of the angles of internal frictionϕ max/ϕ max ≥1.1 should be fulfilled) — the Chugaev method.

The ascending branch is the part of the surface of sliding whereτ 8 is directed toward retaining the sliding wedge;ϕ 0,ϕ b are the values ofϕ i on parts of the surface of sliding passing through the base and body of the slope.
