Cohesion-damage-friction constitutive model of the frozen soil-structure interface

Abstract

Abstract: The constitutive model of the interface between frozen soil and structure is very important to the design, analysis and numerical simulation of engineering practice in cold regions. A one-dimensional constitutive model of the interface between frozen soil and structure was established by coupling the cohesive damage model and the friction model. Based on the meso-mechanical assumption, the mechanical response of cemented ice at the interface and the friction mobilization, the representative elementary area of the interface was divided into damaged part and non-damaged part. During the shearing of the interface, the non-damaged part of the representative elementary area was assumed to be elastic deformation. The friction effect was mobilized during the representative elementary area transform from the initial undamaged state to the fully damaged state. The damage evolution equation and the friction evolution process of the representative elementary area were established based on the basic kinematics hypotheses of the interface, and the constitutive relationship of the interface was established according to the homogenization method. The parameters in the model have clear physical meanings and are easy to obtain from the test data. The numerical results show that the model has a good fitting effect on the both strain softening curve and strain hardening curve of the interface, and the key parameters in the test curve can be reflected in the model.
