Schematy obliczeniowe dla metody Falleniusa (przy braku wypełnienia zbiornika).
1).Linia położenia najniebezpieczniejszych środków obrotu
H = 10 [m.]
4,5H = 45 [m.]
α = 26034`
δ1 = 250
δ2 = 350 (wartości odczytano z tabl.10-2 Z. Wiłun, Zarys geotechniki, 1987, W-wa)
2).Wyznaczenie najniebezpieczniejszego środka obrotu : F = Fmin
Równanie paraboli : F(x) = ax2 + bx + c
F(3,369) =0,9 a = 0,039
F(4,280) =0,78 b = -0,389
F(6,426) =0,7 c = 1,829
Równanie paraboli : F(x) = 0,039x2 -0,389x +1,829
F'(x) =0,078x -0,389 = 0 ⇒ x = 5,721
Fmin= F(5,721) = 0,716
Najniebezpieczniejszy środek obrotu wypada pomiędzy punktami O2, i O3. Płaszczyzna poślizgu wypada więc pomiędzy płaszczyzną 2 i 3. Wskaźnik stateczności „F” wynosi 0,716.
