| Abstract: | The principle of geostress measurement by hollow inclusion triaxial strain gauge is systematically studied, and the calculation formulas for processs of measured data are derived. The correcting factors Ki, used to correct the error caused by the strain gauges not cemented directly to the surface of rock in the borehole, is discussed. It is also analyzed that the errors of assumed values of correcting factors Ki lead to the errors of geostress measurement. |
