摘要:: 本文根据横向铰接料板桥结构力学性能的特点，认为跨内径向弯矩是斜板桥结构设计计算的关键之所在．采用与等跨简支架跨中弯矩相比拟的方法，求出将斜板桥离散为单块板（粱）时的等效荷载横向分配系数．从而将斜板跨内径向弯矩的求解简化为单跨简支架跨中弯矩的计算，解决了由斜板间相互铰接而给计算带来的困难，较其它实用计算法更加简捷、实用．文中给出了一个抖板桥算例，并通过与经典的有限元法、有限条法及其它实用计算方法的计算结果的比较，证实了本文方法的正确性和实用性．

Abstract:: Based on the characteristics of the mechanical properties of the horizontal hinge of the board bridge structure, this article believes that cross -inner radius bending moment is the key to the design calculation of the slanting plate bridge structure. Compared with the method of curvature of the bending moment in the other span stent, the equivalent loading coefficient of the equivalent load of the oblique board bridge into a single plate (beam) is found. As a result, the solution of the diagonal plate cross -inner radial bending momentum is simplified into the calculation of the single -span simplified bracket -to -medium bending moment, which solves the difficulty brought by the calculation between the inclined plates, which is more simple and practical than other practical components. A shake board bridge calculation is given in the article, and the comparison of the calculation results of the classic finite element method, limited method and other practical calculation methods confirms the correctness and practicality of this method.
