Modulus of Subsoil Reaction According to Menard
Based on the results from experimental measurements () of soil response loaded by rigid slab Menard derived the following expression for :
MPa], if necessary it can be substituted by oedometric modulus of soil [
characteristic length depending on a depth of fixed-end structure, according to Menard assumed at a depth of 2/3 of length of fixed-end structure below final depth of sheeted ditch [m]
rheological coefficient of soil [-]
Approximate values of rheological coefficient of soil α
