Abstract: An in-situ stress measurement and a rock mechanical test under different confining pressures and statistics of structure properties of rock mass in a deep borehole in Beijing have been carried out to research the relation between in-situ stress and rock elastic modulus thoroughly. The results are as follows: the relation between principal stress magnitude and rock elastic modulus shows a positive correlation in granite, but not clear in limestone. In granite, the relative coefficient between principal stress magnitude and revised rock elastic modulus exceeds the relative coefficient between principal stress magnitude and rock elastic modulus. The correlation between in-situ crustal stress magnitude and results of rock mechanical test in high-isotropic rock (e.g. granite) is high, but the correlation in low-isotropic rock (e.g. sedimentary rock) is low.

Key words: in-situ stress, rock mechanical test, rock elastic modulus, correlation analysis
