Abstract
Although hydraulic pressure cells in boreholes have been in extensive use since 1957, methods of data reduction have been slow to develop. Recent research indicates a linear relationship between cell pressure change and rock stress change. In this paper, the logarithm of the cell pressure is related to the stress change in seven elastic materials, and equations derived from this experiment to relate borehole pressure cell data from vertical and horizontal cells to biaxial ground stress changes are presented.
