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
