Abstract

Elastic – plastic balance of the hills massif is examined under the Stavrogin's condition of destruction under symmetric boundary conditions in view of the heterogeneity of a file arising at artificial freezing of friable watery breeds with the help of freezing columns. Formulas for definition of pressure and movings to plastic and elastic areas are received. The border between elastic and plastic areas is found. The area of existence of the decision is determined.
