The calculation of the side pressure coefficient in conditions of the limited stress situation

Abstract

In this article the method of the side pressure coefficient determining in the conditions of limited stress situation is considered. Envelopes of limited stresses circles on the strength passport and the rectilinear envelope in the region of limited extending stresses for different geological conditions are compared. The calculation-graphical method for the side pressure coefficient determining in areas of compressive and extending stresses is given and the comparative analysis of its results is done. It is obtained that the coefficients of the side pressure for the rectilinear and curvilinear envelopes in the zone of extending stresses are equal to each other.
