Based on the elastic properties of corrugated steel plate culverts and the Canadian code for corrugated steel bridges and culverts,a calculation method for structural deformation of corrugated steel plate culverts was derived by taking the semi-circular arch as an example.Then,using this method,the vertical and horizontal deformation of typical sized circular corrugated steel plate culvert structures un-der the action of filling with the change of filling height was calculated,and the results were compared with the actually measured results.The comparison results show that the proposed calculation method can basically simulate the shape change of the corrugated steel plate culvert structure.Except for the large difference in vertical deformation of the arch crown when the filling height is small,the calculation results of this method are basically consistent with the measured values under other working conditions,indicating that the deformation calculation method of the corrugated steel plate culvert structure pro-posed in this paper is highly reasonable and can be used as a reference for the structural design of corru-gated steel plate culverts.
