%X A method of 3dimensional geostress measurement by hydraulic fracturing technique in one borehole is suggested. It is based on utilizing reopening tests of the preexisting fissures in borehole. The specific calculating formulas are derived for two cases in which reopening tests of preexisting fissures are only utilized or it is combined with conventional hydraulic fracturing in intact rock section. These methods possess the advantage of easy practial operation.
