Stress state of the Earth crust pdf

Zhabko A. V.

The article is devoted to the analytical determination of the natural stress field in the Earth’s crust. On the basis of earlier author’s research it is shows the equilibrium condition of the prism displacement, as well as the geometry of most dangerous sliding surface is proved. The criterion of limiting equilibrium (strength) is proposed. The calculated relations for initial field of natural stress based on elastic-plastic nature of the deformation of rocks.

Keywords: equilibrium conditions; functional; differential equation; state of stress; strength criterion; gravitational and tectonic components of the horizontal stress field.
