摘　　要：从汶川地震中与挡块相关的典型震害着手,分析了挡块在桥梁抗震中的作用,进而提出优化设计理念,并从国内外挡块设计的发展及中外规范比较出发,探究了挡块设计的优化方法,同时结合实例,提出了合理的挡块优化设计方法。In this paper,the typical damage about shear key from Wenchuan earthquake was focused,then analyse the role of shear key in earth-quake resistance and present the concept in optimum design for shear key. Development of shear key from abroad was analysed and codes of Chi-na and American were compared,in order to explore the optimum design for shear key,combining with engineering examples,then present the optimum design for reasonable shear key.
