The Coefficient of Subgrade Reaction was introduced in the form of a Set of Springs model by Winkler during the 19th century. In this model, the subgrade is modeled as a set of springs with a stiffness of
calculation of shear and moment distributions in the foundation.
The model has been used by structural designers for decades, who have improved it to calculate stresses under flexible foundations, like continuous footings or raft foundations, as well as concrete pavements subjected to wheel loads. Therefore, proper estimation of
scale calculations. Among the commonly used equations for correlating the PLT results to
for large raft foundations are those proposed by Terzaghi (1955).
The main objective of this paper is investigating
The results indicate that the Terzaghi (1955) equation for Clay estimates an acceptable value for
in cemented granular soils similar to Tehran alluvium.
