摘要
抚边河断裂距大渡河干流大型水利工程金川水电站仅35km,因其近期较强的地震活动性成为电站区域稳定性评价的重要考虑因素。研究从地球物理、地震、地质、地貌等方面分析了断层存在的证据和活动性,首次发现断层切割第四系的直接证据。分析了断层活动性对大坝建设的影响。
It is only a 35-km distance from the Fubian River fault to the large-scale Jinchuan hydropower station, Dadu River, Sichuan. Thus the currently intense seismic activities should be considered as important factors in the evaluation of the stability of the hydropower station. The evidence and activity of the fault are examined on the basis of geophysics, seismology, geology and geomorphology. The fault has been found, for the first time, to dissect the Quaternary strata, however it has no harm to the safety of the hydropower station.
