Abstract
It is generally understood that the most well-known constitutive relations for the overconsolidated clay are based on the theory of isotropic elasticity. When the clay is isotropic linear elastic, the coefficient of the earth pressure at rest is independent of the overconsolidation ratio (OCR). However, most experimental evidences indicate that the value of K0 varies with OCR.
It is shown that anisotropic elasticity may be considered as one of suitable soil models to predict the horizontal stress of overconsolidated clays. The prediction of the model will be compared with the result of K0 swelling test.
