Studying The Mechanism Of Reservoir-induced Earthquake

The reservoir-induced earthquake magnitude is usually!low but its epicentral intensity is high and is nearby important equipments. So it can destroy seriously project and induce secondary disasters. The author is studying on the mechanism of reservoir-induced earthquake in order to predict it. The research results include five aspects:1. Reviewing the research situation of reservoir-induced Earthquake and introducing its characters and cause-condition.2. Analyzing the propagation behaviors for open and close crack, the author gain that normal fault is more dangerous to earthquake than reverse fault and glide fault.3. Appling fracture mechanics to discuss reservoir-induce earthquake mechanism, the author observes the characteristic of surface crack and gains the stress intensity factor induced by the pressure of rock, water and osmosis. Finally the author explains the mechanism of tectonic earthquake.4. The author utilizes Catastrophe theory to explain the high magnitude mechanism by non-linear resonance model.5. In order to know the stress distributing of river, the author simulates the field by finite element analysis.
