Véas-Souche theory

Calculation of the force Nc follows from graphs published by Véas and Souche (see literature). The graphs for the determination of the critical normal force Ncr are constructed for dimesionless quatitites ω,m:

where: lP - micropile length
EaIa - bending stiffness of micropile reinforcing tube
ω - ratio of free length of micropile (from beginning of base) and its length in soil
Erd - design value of modulus of horizontal reaction

where: Er - reaction of soil in horizontal direction
Fw - coefficient reducing the value of Er  (Fw = 1,25)
