the results of deep artificial permafrost 's tri-axial compression test showed that the stress-strain relationship of deep original frozen clay presents a character that is weak and soft From the view point of engineering application , the paper gives a exponential model containing two parameter, Comparative analysis showed that the model not only gives a good description of frozen clay stress-strain relationship before peak stress, but also has the advantages of less model parameters, easy to determine and clear physical meaning. The analysis results showed that the model parameters a linear increase with the decrease of the temperature, and the change rule of parameters is contrary.
