摘　　要：鉴于目前胶凝砂砾石料的动力特性研究较少,关于胶凝砂砾石坝动力工作性态的认识尚不能满足设计、施工及运行管理的需求,基于试验研究提出的新型胶凝砂砾石料动力本构关系,分析了该坝型的抗震工作性态,研究了坝坡及胶凝剂含量对大坝动力响应的影响。计算结果符合实际工程的一般规律,可为该坝型的工程实践提供参考依据。In view of relatively less research on dynamic characteristics of CSG material at present, the cognition of CSG dam＇s work behavior cannot meet the requirements of design and construction, operations management. Based on the new dynamic constitutive relationship of CSG material suggested by experimental study, the seismic resistance of CSG dam is analyzed. Furthermore, the impact of dam slope and the content of gelatinizer on dynamic response of the dam is studied. The computing result accords with the general law of actual engineering, so it can provide a reference for engi- neering practice of similar dam.
