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.
