WebThe most commonly used value is the modulus of subgrade reaction, k. This value is not directly related to bearing capacity and k does not tell the designer if there is compressible or expansive soil. What it does is indicate how stiff the subbase/subgrade is over small deflections (about 0.05 inches). Web22 Jun 2009 · Coming to your question: Please note that the unit for bearing capacity is KN/m2, whereas the unit for Subgrade modulus is kN/m3. It is also called as soil spring constant k = Pressure/settlement. It is normally used to solve problems of beams on elastic foundation using Winkler Model.
