| 摘 要： | In this paper, we focused on earthquakes with Ms ≥ 7.0 in the Chinese mainland from 1900 to 2012, calculated the lunisolar tidal Coulomb failure stress on the seismic fault plane and got the tidal phase through Schuster＇s test, then quantitatively analyzed the correlation between strong earthquakes in the Chinese mainland and tidal Coulomb failure stress. Research shows that among 57 strong earthquakes with focal mechanism solutions, over 71.9% took place within the tidal loading phase, with the p-value of 3.83%, indicating that strong earthquakes with Ms ≥ 7. 0 in Chinese mainland have a certain correlation with lunisolar tidal Coulomb failure stress. In the active period, the p-value is 4. 56%, 75.5% of earthquakes occurred in the tidal loading phase zone, and 50% of earthquakes occurred in the quiescence period, indicating that strong earthquakes in the active period were obviously triggered with the tidal Coulomb failure stress loading.
