| Abstract: | The amplitude and peak period of earthquake wave spectrum increase with elevation rising on both sides of valley in the Wujiangdu reservoir Jiaojiaping earthquake area. Elevation rises a hundred meters, the amplitude increases about one times. Peak period of spectrum increases 0.1-0.3 second. The amplitude is related with earthquake incident direction. The amplitude on the sides nearer to epicenters is much larger than opposite one. According to relation between intensity and displacement amplitude of earthquake, it is suggested that if build a hundred meter dam, the intensity at the top would be 0.5-1.0 degree higher than in the bottom. |
