THE FINITE ELEMENT STRESS STATE ANALYSIS OF UNDERGROUND HYDRAULIC ERECTIONS TAKING INTO ACCOUNT THE ANISOTROPY OF THE MEDIUM

Abstract

In this article, the stressed state analysis of a transverse-isotropic rocky soil near a hydrotechnical tunnel is carried out. The cross section of the tunnel is circular. The load considered in the analysis is the self-weight of the surrounding soil. The analysis is carried out for various resilient characteristics of the soil and in the orthogonal directions for various slopes. The slope of the plane of isotropy models a sloping bedding of layers of earth. The slope of the plane of isotropy models a sloping bedding of layers of earth. The tangential stresses are defined at the entry line. This allows estimating the strength of the surrounding soil for various laying depth
