Abstract

A borehole stressmeter which records stress-relief displacements via double exposure holography is under development. Briefly, the stressmeter records a three-dimensional displacement field resulting from the drilling of a small stress-relieving hole in the borehole wall. Data is stored in the form of a fringe pattern superimposed on the image of the borehole wall and the stress-relief hole.
