| Abstract: | Taking the Danjiangkou Reservoir as an object, a finite-element model is established according to seismic geological structure of the reservoir area. Then tectonic stress field and crust stress field are calculated applying the software of Ansys before the reservoir impoundment; their distribution characteristics and plastic strain features in reservoir area are analyzed. The influence of tectonic stress field on reservoir-induced earthquake is discussed. The research achievement can promote the study of mechanism of reservoir-induced earthquake and be for reference of researvoir-induced earthquake forecast and safe evaluation after the water level of Danjiangkou Reservoir rises. |
