摘　　要：针对5.12汶川大地震中紫坪铺水电站#2泄洪排沙洞进水塔出现的严重损伤,基于地震部门新核定的场地地震动设计、校核参数,采用反应谱法抗震复核分析进水塔结构地震动力响应,并评估了强度、刚度与抗震性能,指出抗震薄弱部位,可为加固设计提供参考。In 5.12 Wenchuan earthquake,the intake tower of spillway tunnel #2 for Zipingpu hydropower station appears a certain degree of damage.Based on newly approved earthquake ground motion design and checked parameters by seismic sector,the response spectrum analysis method with anti-seismic check is used to analyze seismic dynamic response of intake tower structure.At the same time,the strength,stiffness and earthquake resistant behaviour of intake tower are assessed and the anti-seismic weak position is pointed out.Thus it provides reference for hardness design.
