重庆乌江某电站大水位差重件码头平面与结构形式探讨

Layout and structural type of heavy-lift wharf with a large range of stage in Wujiang river of Chongqing

针对重庆乌江某电站重件码头选定港址的地形地貌、水文及地质条件,在长江上游重件码头设计中首次提出了码头平面布置采用"陆域工作平台+起重机安装平台+系靠船墩"的新型布置方式、重大件装卸采用"垂直起吊+360°全回转装卸"的工艺方案和系靠船采用船闸固定式系靠船柱水工结构方案,可实现重庆乌江流域最大水位落差20 m和日变幅达5m停靠船及装卸作业的要求,同时解决了港址后方陆域条件差及最大起重高度达73 m等难题,对后方陆域条件受限制的大水位差内河码头的设计有一定参考价值。

According to the topography,hydrology and geological conditions of the chosen site a heavy cargo wharf of a power plant in Chongqing Wujiang river,we propose a new type of wharf on the upper Yangtze river,with a new layout of＂land work platform plus crane installation platform plus berthing pier＂,heavy cargo handling with ＂vertical lifting and 360° rotary loading and unloading＂,and fixed berthing pier structure on the lock,which can meet the demands of berthing and handling operations in Wujiang river basin of 20m＇s maximum range of stage and 5m＇s maximum stage fluctuation within a day,and solves the difficulties due to the poor condition of the back-up land and the largest lifting height of 73 m,etc.It may serve as a reference for the design of inland wharves with a large range of stage and restricted back-up land conditions.
