Identification technology based on constitutive model database of geotechnical material

Constitutive model back analysis is an important aspect and difficult point in geo-material back analysis, in which the identification of geo-material constitutive model is precondition and foundation of constitutive model back analysis. Based on the present circumstances about the model identification methods of geo-material constitutive researching, it begins with the fundamental principle of identification, puts forward the researching train of thought taking the geo-material constitutive model database as a platform, combining several identification algorithms.
