摘　　要：大跨度斜拉桥的施工中,为了保证桥梁结构施工安全,通常要设置临时墩。临时墩具体型式,通常根据桥梁的结构特点及当时的施工具体外界环境而定。湖北鄂黄长江公路大桥水深、流急、覆盖层薄,根据这些特定的条件,采用特殊的淹没式钢围堰临时墩,保证了整个大桥施工安全顺利的进行。本文就大跨度斜拉桥淹没式钢围堰的设计与施工做一定的探讨,为以后类似桥梁的建设,提供一定的参考。During construction of long-span cable stayed bridges, the temporary piers are generally constructed to ensure the safety of bridge structure construction. Selection of type of the temporary piers usually depends on the structural characteristics of the bridges and the outside environment of construction. During construction of Ehuang Yantze River Bridge in Hubei, a special submerged steel cofferdam was used as a temporary pier because the bridge locates in a place with deep water, torrent and thin covering layer, so the construction safety of the bridge is guaranteed.
