摘要
根据平面弹性力学极坐标系内的控制方程或其混合变分原理，可导出状态方程。然后，应用三角级数来构造涵洞的应力与位移函数，即状态变量函数，建立涵洞的状态方程，计算涵洞的应力与位移值。
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.
