介绍了国内在建的2座主跨超千米的3塔悬索桥中塔塔型的区别,对3塔悬索桥中塔的结构行为特性进行说明,并结合各桥的建设条件对2桥中塔塔型的适应性进行了分析,分析结果认为,泰州大桥和马鞍山大桥根据各自的建设条件和通航要求,分别采用了适合自身特点的中塔塔型。对于千米级3塔悬索桥,可采用纵向人字型钢中塔和独柱型钢-混组合塔,但前者在构造、受力和经济上优于后者。
介紹瞭國內在建的2座主跨超韆米的3塔懸索橋中塔塔型的區彆,對3塔懸索橋中塔的結構行為特性進行說明,併結閤各橋的建設條件對2橋中塔塔型的適應性進行瞭分析,分析結果認為,泰州大橋和馬鞍山大橋根據各自的建設條件和通航要求,分彆採用瞭適閤自身特點的中塔塔型。對于韆米級3塔懸索橋,可採用縱嚮人字型鋼中塔和獨柱型鋼-混組閤塔,但前者在構造、受力和經濟上優于後者。

The paper introduces the differences of the middle pylon between two three pylons suspension bridges whose main span are over 1 kilometers in China,describes and analyzes the characteristics and adaptability of the middle pylon for three pylons suspension bridges combining with the construction conditions of each bridge.The results demonstrate that the adaptive type of middle pylon is adopted based on their own characteristics for Taizhou bridge and Maanshan bridge respectively in accordance with their construction conditions and navigation requirements.For thousand meter scale suspension bridge with three pylons,it can use vertical Y-shape steel pylon and steel-concrete composite pylon with single column,but the former is better in structure,stress state and economic.
