摘　　要：曼宁公式在河道阻力计算中应用广泛,为涉水工程阻力研究奠定了理论基础,但因其来源于工程经验,公式自身尚存量纲不和谐及影响因素不明确的缺陷,对曼宁公式的上述缺陷进行了尝试性改进,初步建立了量纲和谐且经分形细化的曼宁公式。Manning＇s formula has been widely used in the calculation of the river channel resistance, and it establishes the theoretical foundation for water project resistance studies. However, since it is an empirical e- quation derived from engineering experiences, the formula still has some flaws such as non-uniform dimension issue and uncertain factor problem. This paper attempts to address the above-mentioned flaws, and some pre- liminary results have been achieved through dimension harmonization and fractal refinement to improve the Manning＇s formula.
