الملخص EN

The nonlinear constitutive relations of clay are investigated considering different initial conditions.

Highly compressible clay is selected as the test sample.

Two groups of tri-axial compression tests are performed, respectively, after K0 consolidation and isotropic consolidation.

On the basis of the framework of E~v model, a uniform nonlinear constitutive model is proposed by fitting the test data.

With the average slope of the unloading-reloading curve selected as the unloading modulus, the unloading function is constructed as the loading-unloading criterion.

Moreover, a comparison between the experimental stress-strain curves and the results predicted by the constitutive model is made.

It is shown that the prediction is reasonable, which can reflect the stress-strain behavior of the soil under the K0 consolidation and isotropic consolidation conditions.

The maximum relative error of the two series of curves is not remarkable, less than 6%.
