Abstract: The development of new river channel projects and its design is important to solve difficult control of the Yellow River regime and high emergency costs problem.Analyze the defects of traditional engineering and elaborate the structural form of the new steel pile dam project combining with data from 2021 and 2022,showing that the combined pile dam demonstration project in the downstream river can achieve the river control goal and solve the problem of large shortage of funds for rock throwing and rescue.In the engineering design of Shaojiaqiao and Hongyazi prototype test, the steel structure shaped dam's sheet pile length of 12m and the lower steel pipe pile length of 19m were determined according to the overturning stability calculation; The design of steel permeable pile dam in the form of double-row and overall interconnection in the lower extension of the control guide can increase the shape of the support area, which can effectively strengthen the overall stability while improving the effect of slow flow and siltation and restricting flow and sending guide.
