摘要
Abstract
Pipe jumps are often seen at pumping stations near hydraulic tunnels.At this time,the water flow in the pipe is complex,which may even cause the resonance of the buried pipe and lead to the damage of the lining structure.In this paper,ABAQUS Finite Element Calculation Software is used to calculate the eigenfrequency of steel pipe under the action of hydrodynamic pulsation pressure.The natural vibration characteristics of steel pipe are studied.On this basis,the transient response of the hydraulic jump pressure of the steel pipe is analyzed.The influence of hydraulic jump pressure on the displacement and stress state of the steel pipe lining structure is explored.In addition,the influence law of the pulsating pressure parameters is analyzed.关键词
