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（ＤｕｎｃａｎＣｈａｎｇ 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， 该坝不会出现液化现象 According to the vibration consolidation model of saturated solid-liquid two-phase medium, the nonlinear static constitutive model (Duncan-Chang model) and the Mohr-Coulomb strength criterion and the soil dynamic model (Hardin model) The finite element analysis of the dynamic response under the action of earthquake was carried out, and the process of pore pressure growth and dissipation was obtained. Analysis shows that the dam does not liquefy
