混凝土重力坝在地震荷载下的稳定分析
|
摘要
采用混凝土损伤塑性本构模型,利用有限元分析软件ABAQUS进行混凝土坝的结构计算,分析某混凝土坝在地震荷载下的响应,分析结构的稳定性和任意荷载作用下结构的破坏情况。计算结构表明:采用混凝土损伤塑性本构模型,利用有限元分析软件ABAQUS进行混凝土坝的结构计算,可以更加直观反映混凝土坝的应力、应变和整个坝坡破坏发展过程。计算实例中的混凝土大坝整体稳定性符合设计要求。
This paper introduces concrete dam structure calculation,using the finite element analysis software ABAQUS,combining the plastic constitutive model of concrete damage,and analyses the reaction of a concrete dam under earthquake loading,and its structural stability and structural damage under any load conditions.The results show that: The above method can be more directly reflect the stress,strain and the entire slope damage process of the concrete dam.The overall stability of the concrete dam in the example meets the design requirements.
