Abstract:A comprehensive review has been performed on the study of the reservoir-induced earthquake of the Three Gorges Project(TGP),including the history,means and methods,the basic viewpoints and main conclusions proposed before project commissioning. The focus is put on the description of the seismic activities recorded by the high-precision monitoring station networks since the reservoir step-impoundment of the project in 2003,classification of all the recorded shocks. Analyses of the distribution,characteristics(including the frequencies,intensities and distribution in time and space) and tendencies of the seismic activities are introduced. Through the analysis of the seismic activities after the TGP impoundment;the observation data are used to compare with the conclusions of at pre-construction phase;and a lot of important new information has been obtained. For example,a large number of earthquakes are of water-filling induced collapse-typed of karst caves or abandoned mines,which are dominated by micro- or extreme-micro earthquakes and distributed with obvious localities. Deformation of bank slopes can also be recorded as shocks. The climax of reservoir-induced earthquakes of tectonic type obviously lags behind those of nontectonic-type;and the attenuation tendency of the reservoir-induced earthquakes of above two types is obvious. These data will not only enhance the prediction analysis of TGP reservoir-induced earthquakes,but also enrich the information for study of reservoir-induced earthquakes. On the basis of the above-mentioned studies,a prediction is made on the future tendency of the TGP reservoir-induced earthquakes when the reservoir water level further rises. Analysis and research also are drawn that a certain degree prediction of reservoir-induced earthquake for a specified dam project could be made based on a comprehensive geoseismical research and a large amount of seismic-activated information recorded by the high-precision monitoring station networks. The paper can also provide a comprehensive response to the debating issues related to the TGP reservoir-induced earthquakes.
