Abstract: In the design of the slabs for the high pile warfs of the beam-slab structure, the slabs are divided into the single and double acting slabs in the standard specifications of the harbor engineering, and the bending moment occurs in one or two directions of the axe center when the slabs are acted on by the loading, and an idea of the width of the efficient range of loading is introduced into the single acting slabs to simplify the calculation.In this paper, on the basis of the elastic theory and the present tests the idea is discussed for the slabs,the problems in the use of the standard specification are pointed out, and suggestions about different load, width-span ratio, and the kinds of the slabs are made when the slabs of the high pile warfs are designed, which have some technic economic worth for the design of the high pile warf slabs.

Key words: single acting slab, double acting slab, beam with unit width, width-span ratio, width of efficient range of loading

摘要： 在高桩码头面板设计中,港工规范划分了单、双向板,并对单向板引入有效分布宽度的概念,以使简化计算。本文在理论和现有的试验基础上对上述概念进行了探讨,指出了规范在运用中存在的问题,提出了面板设计应考虑不同荷载、不同的宽跨比、不同的板型的设计建议,这对面板设计有一定的技术经济价值。
