用数学解析方法对桥梁中正交异性桥面进行了位移及内力分析，将其结论与其它数值方法（有限元法、插分法）进行比较，证明是准确的
The displacement and internal forces of the orthotropic bridge deck in the bridge were analyzed by the mathematical analysis method. The conclusions were compared with other numerical methods (finite element method, interpolation method) and proved to be accurate.
