摘　　要：基于有限元方法,以南太湖大桥为例,考虑有无辅助墩两种不同的结构形式,通过建立空间动力计算模型对独塔双索面预应力混凝土协作体系斜拉桥进行动力特性计算与分析,以促进预应力混凝土斜拉桥动力特性的研究。Based on finite element method and considering the two structure designs with or without subsidiary piers, this paper takes the south Taihu Bridge for example calculates and analyses the dynamic performance of the single tower and double-cable-plane prestressed concrete cable- stayed bridge by establishing a space power computation module, so as to promote the study of the dynamic performance of prestressed concrete cable-stayed bridge.
