| Abstract: | Based on control equations of plane elasticity in polar coordiate system,and it's mixed variational princple .The triangle series are used to consist the functions of stress and displacement, e.i. state variable functions, and the state equations of culvert are formulated. The stresses and displacements of culvert are calculated. |
