Abstract: Hydrodynamic pressure and shear force on the surface of floating structure are important factors affecting its security and stability during the running process in finite flowing water. In this paper, orthogonal design and CFD simulation are used to explore the effects of different structural parameters and hydraulic factors on the surface force of floating structure. The results show that floating structure scales have a significant effect on the hydrodynamic resistance and shear force. The vertical position of floating structure, discharge per unit width and downstream water level have no significant effects on the hydrodynamic resistance, while these play an important role on shear force. In addition, regression mathematical models describing the relationship between factors and the hydrodynamic resistance and shear force have been set up, respectively. The research methods and results of this paper can provide a reference for designing the stability of the floating structure during its operation
