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.
