摘要
Abstract
Wudongde Hydropower Station is located in seismic active zone in southwestern China. The terrain in the reservoir area is steep, where faults and structure are developed and the lithology is complicated. The reservoir-induced earthquake is an important engineering geological problem. In order to understand the natural seismic background characteristics in Wudongde Reservoir area, the temporary seismic network covering 50 km in the reservoir area from Jiaopingdu to the dam site was estab-lished. On the basis of the historical earthquake data in the reservoir area and nearby regions, observed data by seismographs since 1965, the seismic background characteristics is further studied. The results show that Wudongde Reservoir area is a seismic moderate area, mostly microseism with the maximum magnitude of 6. 75 and provide basis for forecast and discriminant of reser-voir-induced earthquake after reservoir impoundment.关键词
