| Abstract: | The confining pressure test is an important and essential test to geostress measurement with hollow inclusion triaxial strain gauge. The calculation formulas of elastic modulus to participate processing of measured data are derived minutely based on the test data. The release strains are corrected to achieve greater reliability of measured geostress results by using the results of confining pressure test. A practical example is presented to show the availability of the study result. |
