The mechanical properties of corrugated steel pipe culverts (CSPCs) for highways depend on the elastic modulus of the foundation soil, the backfill height, and the culvert parameters. Evaluating the stress and deformation characteristics is crucial for the design of CSPCs. A three-dimensional finite element model and field test were used to investigate the effect of various parameters on the earth pressure and deformation of the CSPC during construction. The finite element method results were compared with the test results, and the stress and deformation characteristics of the CSPC were analyzed in detail. As the wavelength increases, the CSPC experiences more deformation, and the earth pressure at the top of the pipe decreases. When the wavelength and thickness are fixed, the displacement of the CSPC decreases, and the earth pressure at the top of the pipe increases with an increase in the wave height of the CSPC. When the wave height and wavelength are fixed, the deformation of the pipe culvert decreases, and the earth pressure at the top of increases with an increase in the pipe culvert’s thickness. These results provide new insights into the construction, design and maintenance of CSPCs.

公路波纹钢管涵洞（CSPC）的力学性能取决于地基土的弹性模量、回填高度和涵洞参数。评估应力和变形特性对于 CSPC 的设计至关重要。采用三维有限元模型和现场试验研究了施工过程中各种参数对CSPC土压力和变形的影响。将有限元方法结果与试验结果进行比较，详细分析CSPC的应力和变形特性。随着波长的增加，CSPC 发生更大的变形，管道顶部的土压力减小。当波长和厚度一定时，CSPC的位移减小，管顶土压力随着CSPC波高的增加而增大。当波高和波长一定时，管涵变形减小，管涵顶部土压力随着管涵厚度的增加而增大。这些结果为 CSPC 的建造、设计和维护提供了新的见解。
