TL;DR: Although no mathematical theory accounts for the wide range of in situ stress patterns encountered throughout the world, empirical relationships for sub-continental areas have been established as mentioned in this paper, where the authors have tabulated and plotted reported stress measurements where the data including both vertical stress and an average horizontal stress or two orthogonal horizontal stresses.

Rock Mechanics for underground mining: Third edition
B. H G Brady,E. T. Brown +1 more
- 01 Jan 2006
TL;DR: Although Rock Mechanics addresses many of the rock mechanics issues which arise in underground mining engineering, it is not a text exclusively for mining applications as discussed by the authors, and it consists of five categories of topics on the science and practice of rock engineering: basic engineering principles relevant to rock mechanics; mechanical properties of rock and rock masses; design of underground excavations in various rock mass conditions; mining methods and their implementation; and guidelines on rock mechanics practice.

TL;DR: In this article, the authors present details of the new WSM database release 2016 and an analysis of global and regional stress pattern, and show two examples of 40 degrees-60 degrees S-Hmax rotations within 70 km.

Fault geometries in basement-induced wrench faulting under different initial stress states.
TL;DR: In this paper, the Coulomb-Mohr theory of shear failure is used to rationalize the sequence of faults and three-dimensional geometry of wrench failure. But the model is not suitable for the case of a large number of shears.

Importance of anisotropy when estimating and measuring in situ stresses in rock
TL;DR: In this paper, the effect of anisotropy on the analysis of over-coring measurements with cells similar to the CSIR Triaxial Strain Cell is discussed, and the authors show how to account for both anisotropic (intact and joint induced) and the curvature of the Earth when estimating in situ stresses in rock masses.

The hydrofracturing stress measuring method and recent field results
TL;DR: A recent development in the area of stress measurements in rock is the use of hydrofracturing as discussed by the authors, which directly determines average stresses over large areas by recording two hydraulic pressures, one necessary to crack open a segment of the test-hole and the other required to keep the fracture open.

The state of stress in the upper part of the earth's crust
TL;DR: In this paper, the authors present new results of absolute rock-stress measurements performed in the upper part of the earth's crust as a contribution to the discussions of the problem of 1) whether the earth is expanding or contracting and 2) whether continental drift and convection currents exist.

The determination of the complete state of stress in rock in a single borehole—Laboratory and underground measurements
TL;DR: In this paper, the authors defined the six stress components which are measured in the single-borehole technique and further details of the borehole strain cell are given and the technique of using it in the field is described.

Global Measurements of Absolute Stress
TL;DR: By absolute rock stress measurements the existence of a general horizontal compressive stress field in the Earth's crust is demonstrated; the sum of the horizontal principal stresses linearly increases with depth.
