Abstract

In order to explore the parameter effect of a composite arch culvert with corrugated steel plate and concrete, based on the engineering background of a composite arch culvert, the influence rules of four parameters, namely fill height, pipe diameter, wall thickness, and uneven settlement, on the stress and deformation of the arch culvert were analyzed based on the control variable method. The results show that the deformation and stress of the arch culvert are positively correlated with the fill height h and pipe diameter R. When h < 25 m, the deformation and stress increase linearly with the increase in the fill height, and when h > 25 m, the deformation and stress increase in a curve form. When R < 4 m, both of them increase linearly with the increase in pipe diameter, and when R > 4 m, the curve increases, and the change rate accelerates obviously. When the wall thickness T is 2–6 m, the deformation and stress increase linearly. When T > 6 m, the stress of the corrugated steel plate is basically unchanged. The horizontal uneven settlement has an obvious influence on the stress of the arch culvert, and increasing the pipe diameter can effectively control the additional internal force caused by the uneven settlement.
