Use of the Correlation Process Between Compressibility Diagrams Laboratory and Numerically Obtained to Valuate of the K_o^oc Values

Abstract eng:
The oedometric tests that belong to fundamental laboratory tests are carrying out while the subsoil stiffness in uniaxial strain state corresponds to conditions for the real building object. For subsoil constitutive model allowing for loading history in the past the profile of the lateral stresses is demanded. Distribution of these stresses for subsoil model is usually in accordance with literature findings set up. Correlation for compressibility diagrams obtained: - in laboratory for clay taken from the depth 20m to 50m, and - numerically in MCC model (for parameters λ, κ laboratory obtained) may lead to evaluation: - of the Ko value, and - subsoil layer compressibility value.
