SYMMETRIC ELASTICITY PROBLEM FOR A LAYER WITH TUNNEL CAVITIES COVERED WITH A DIAPHRAGM

摘要

A new procedure is proposed for the solution of mixed three-dimensional symmetric problems of the theory of elasticity for layers weakened by through tunnel cavities. The boundary-value problem is reduced to a system of 3k (k = 1, 2,...) one-dimensional singular integral equations. The results of numerical evaluation of the characteristic stresses are presented.
