EFFECT ANALYSIS OF RESERVOIR-CANYON TOPOGRAPHY ON GROUND MOTION
摘要
Abstract
The effects of reservoir-canyon topography on the ground motion are analyzed with finite element method and following are obtained. 1) The change of the height, the angle and the ratio of height to width of topographic features affect the peak ground acceleration and the spectrum of analytical model obviously. 2) The water level rising of water side will reduce the peak value of ground motion of the mountain part, and the high frequency components of input seismic waves will be inhibited more obviously. 3) The seismic response is sensitive to the frequency of input seismic waves.关键词
