Abstract:

One of the most important engineering challenges in the design of structure, is the reaction of soil in contact with structure. In engineering design of structures, the subsoil can be simulated by a much simpler system called subgrade reaction model. In order to evaluate the in situ modulus of the clayey deposits of the Qazvin alluvium, the results of a large number of in situ tests carried out by many researchers were analyzed. Vertical plate load tests, standard penetration tests and test pit exploration were conducted on over 170 different locations. The results of the plate load and standard penetration tests are analyzed and discussed. The correlation between subgrade reaction modulus (Ks), modulus of elasticity (Es) and corrected standard penetration test blow counts (N) are presented for clayey deposits of the Qazvin alluvium. Results show that there is a significant correlation between subgrade reaction modulus (Ks) and SPT blow counts.
