土石坝坝顶震陷分析

Analysis of Seismic Deformation on Crest of EarthRockfill Dams

考虑坝顶震陷随机特征，依据现有国内外土石坝震陷实测资料，进行概率分析和统计分析，并与有限元计算的永久变形作比较．研究成果为确定地震区土石坝震陷安全超高提供参考．

In consideration of the random characteristics of seismic deformation on dam crest and in the light of observation data of earthrockfill dams both at home and abroad the probability analysis and statistic analyses are conducted.The value obtained from the probability analysis is compared with the permanent deformation given by FEM. The research may serve as a reference for determining the safety height of earthrockfill dams in seismic zones.
