Abstract: It is a traditional method that box-shaped and egg-shaped buried culverts are designed with given load. The method does not consider interaction between soil and culverts. But in fact, load acting on culverts is changed with relative stiffness of culvert and soil. So a new analytical method for egg-shaped and box-shaped buried culverts is advanced. Winkler model is used for the model of interaction between pipeline and soil commonly. Transfer matrix method is adopted. By the method, the internal force and distortion of pipeline is calculated and its importance is proved to consider soil retained to some stiffness pipe. Finally, it is discussed that model parameters, buried depth and pipe dimension affect to structural distortion and stress. Accordingly, it is more consistent with reality to design culverts by considering interaction between soil and buried culvert pipe.

Key words: egg-shaped and box-shaped culvert, interaction analysis, Winkler model, transfer matrix, calculation method
