摘　　要：以某作业区泊位工程为背景,对长距离引桥的散货码头给排水设计中存在的若干难点问题进行讨论。通过对比相关消防规范,提出散货码头的消防泵房可执行3000 m保护距离的观点,并阐述了单引桥码头宜采用枝状消防供水管网的理念。针对散货码头初期降雨深度取值问题,从保护环境的角度出发,结合当地降雨资料,提出经济合理的取值。码头排水明沟因结构原因无法设置坡度,引入了平坡明沟计算公式。Taking a work area berth project as the background,some difficult problems in the water supply and drainage design of the bulk cargo wharf with the long approach bridge are discussed.By comparing the relevant fire protection codes,this paper offers the view of 3,000 m radius of protection about fire pump-rooms in bulk cargo terminal and the design of fire water pipe branch-shaped network for single approach bulk wharf.Aiming at the problem of the initial rainfall depth value of the bulk wharf,from the perspective of environmental protection,combined with the local rainfall data,an economical and reasonable value is proposed.The slope of the wharf drainage open ditch cannot be set due to structural reasons,so the calculation formula of the flat slope open drain is introduced.
