| Description | This chapter analyzes the factors, which influence the in situ stress state and describes the most common methods for its estimation and direct determination. Ideally, stresses below the earth surface correspond to the lithostatic effect produced by the lithostatic weight. The tectonic movements of the earth's crust significantly change the original lithostatic arrangement, causing important changes in the virgin stress state. Widespread erosion leads to a decrease in the vertical stresses. Grounds have a differentiated stress–strain response depending on their mechanical characteristics and therefore, when two grounds with a strong contrast between their strengths are in contact, there will be a contrast in the in situ stress distribution. This situation is very common when there is an intrusion of a magmatic rock into a stratified medium. The technique to measure in situ stresses by hydraulic fracturing was extensively studied and improved upon by B. C. Haimson in the United States.
