MODELING METHODS FOR INTEGRAL EQUATIONS OF THIN REINFORCED ELEMENTS OF UNDERGROUND BUILDINGS AND TUNNELS

Abstract

In this paper the model of thin reinforcement that takes into account its tension, shear and bending is developed. The model developed is introduced into the integral equation method for study of stress concentration in the wall of partially reinforced tunnel. The numerical results are obtained and analyzed for different values of reinforcement length and relative rigidity.
