摘　　要：鄂东长江大桥为主跨926 m的双塔混合梁斜拉桥,其北主塔墩及近塔辅助墩位于长江北河道内,施工难度较大,水上施工平台及施工通道的设置需满足材料转运、设备布置、人员操作、安全渡洪等需要。针对以上要求,详细设计了临时工程中的栈桥、码头、钻孔施工平台结构。通过搭设合理的栈桥、码头及钻孔平台等水上大型临时结构设施,变水上施工为"陆上"施工。Edong Changjiang River Highway Bridge is a double pylon hybrid girder cablestayed bridge with a main span 926 m. The north pylon pier and the auxiliary pier of the Bridge close to the pylon are located in the north channel of the Changjiang River, the construction of the piers is rather difficult and the arrangement for the working platforms over water and construction access way needs to satisfy the requirements for material transportation, construction equipment and machinery deployment, construction crew operation and safe flood protection. In accordance with the requirements as mentioned, the large temporary works of the construction trestle, wharf and boring platforms have been designed. The rational building of the trestle, wharf and the boring platform makes the construction over water became that ＂on land＂.
