【摘要】 采用非线性有限元法对某沥青混凝土心墙坝进行地震反应分析,以正常蓄水条件下的总静力场作为动力分析的初始应力场,利用大型有限元软件ADINA计算出坝体的绝对加速度反应、相对位移反应、动应力反应、动剪应力反应。计算结果表明:该坝的设计基本合理,具有良好的抗震性能。更多还原

【Abstract】 This paper adopted non-linear element method to analyse a earthquake reponse of one asphalt concrete core dam.Based on total static field in nomal sluice level as initia stress field of dynamic analysis,the paper used a large finite elemene software ADINA to calculate the absolute acceleration reaction,relative displacement reaction and dynamic stress reaction and dynamic shearing stress reaction.Computing results indicated that the design of this dam was basic reasonable and had favorable earthquake-proof behaviour.更多还原
