| Abstract_FL | The shape of the connecting section of the shaft spillway directly affects the flow pattern of the tunnel,the vibration characteristics of the shaft and the energy dissipation effect.At present,the research on the shape of connecting section is mostly single factor,and few multi-factor studies.In engineering design practice,the optimization of shaft shape mostly refers to similar engineering experience,and there is no more systematic optimization method.In this paper,the numerical orthogonal test is used to analyze the sensitivity of the length-width ratio,the contraction ratio of the exit pressure slope and the compression slope ratio of the connecting section.The results show that the length-width ratio has the most significant effect on the outlet turbulent kinetic energy,followed by the compression slope ratio and the lowest contraction ratio.The research results can provide some reference for the optimization of the joint shape of the shaft spillway tunnel in engineering design. |
