Modulus of Subsoil Reaction According to CSN 73 1004 (2020)

The modulus of subsoil reaction for cohesive soil assumes the form:

kde:

Edef

-

modul deformace zeminy [MPa]

d

-

průměr piloty [m]

For cohesionless soil, it is given by:

where:

nh

-

modulus of horizontal compressibility [MN/m3]

d

-

pile diameter [m]

z

-

depth of a given section from original grade [m]

Note: for pile diameter d > 1,0 m, d = 1,0 m

Approximate values of modulus of horizontal compressibility nh for cohesionless soils:
