Identification of constitutive model for rock materials based on immune continuous ant colony algorithm

Abstract

From the generalised constitutive law of rheological constitutive model of rock material, the model identification is transformed to parameter identification. To improve the efficiency of the traditional evolutionary algorithm, a new immune continuous ant colony algorithm proposed by the author is applied in this study, based on which one new model identification method is proposed. Using this new method, a real engineering example is applied to verify the computing ability of the new algorithm. The results show that the effect and efficiency of the new method are very good.
