| Abstract: | On the basis of the data of hydraulic fracturing stress measurement and mechanical property of the drilledcore from the Maoping 800 m bore hole, the failure mechanism of disk core in the bore hole was analysed. Inthis paper, it is considered that the disk core is caused by the declination of principal axis of crustal stress under low crustal stress value. According to the section property of disk core and stress analysis, the form of disk core is tensile failure. |
