摘要
本文根据饱和土体固液两相介质的振动固结模型， 采用非线性静力本构模型（ＤｕｎｃａｎＣｈａｎｇ 模型） 及摩尔库仑强度准则和土的动力模型（Ｈａｒｄｉｎ 模型） 对黑河土石坝进行了地震作用下的动力反应有限元分析， 得到了振动期孔压增长与消散过程． 分析表明，
Based on the dynamic consolidation model of the saturated soil,the Duncan\|Chang Model and the Hardin model are used for the purpose of the dynamic response analysis of the Heihe Earth Dam under the seismic load.The development of the generation,dispersion and dissipation of the pore water pressure in the dam is studied and the identification of the liquefaction of the dam is conducted.The analysis results show that no liquefaction will happen to the dam during earthquake.
