  • In order to study the mechanical properties of the interface between tunnel support structure and surrounding rock in yellow clay area, the basic mechanical test and three-dimensional numerical simulation of the contact surface were carried out, and the development law of the stress and deformation of the contact surface was summarized and analyzed. On this basis, the damage mechanical constitutive model of the contact surface between tunnel support structure and surrounding rock soil in yellow clay area was proposed. The constitutive model is practical and can provide theoretical support for similar projects in yellow clay area.
