CALCUL MASIVE DE ANCORAJ

Pentru dimensionare masivelor de ancoraj s-au folosit urmatoarele formule de calcul:

S = 1.57*d^2*p*sin(α/2)

S - forta dupa bisectoarea unghiului (kgf)

d - diametrul conductei (cm)

p - presiunea maxima din conducta (kgf/cmp)

S ≤ 0.9 * T

T - rezistenta totala a terenului de fundatie

T = T1 + T2

T1 =

T1 - impingerea pasiva a pamantului (kgf)

ϕ - unghiul de frecare interna a terenului de fundatie

12.00

γ - greutatea volumetrica a pamantului (1800 - 1900 kg/mc)

I, h, b - dimensiuni care se stabilisc in functie de tipul masivului de ancoraj

T2 = Q * f

-rezistenta masivului prin frecare pe talpa fundatiei (kgf)

Q - greutatea masivului de ancoraj (kgf)

f - coeficientul de frecare intre beton si pamant

f =(0.2 - 0.3)
