摘　　要：研究了超斜铰接板桥(斜交角大于45°)的荷载横向分布规律,提出了利用经验公式求算超斜铰接板桥荷载横向分布影响线竖标值的方法.采用剪力-柔性梁格法对某桥进行数值模拟,利用有机玻璃模型试验验证其正确性,得出了简单实用的数值模拟方法.对不同板数、不同斜交角的铰接板桥进行数值模拟,进而得出计算超斜铰接板桥横向分布影响线竖标值的经验公式.通过理论解的求算,证明该经验公式实用、可靠.Transverse load distribution of large-angle hinged skew slab bridge was studied,and the method to calculate the influence line of transverse load distribution with an empirical formula was put forward.In order to establish a reliable numerical model,shear-flexible grillage method was adopted,then organic glass model was made to verify the reasonableness of the numerical model.Numerical models of hinged skew slab bridges with different slabs,different skew angles were established to get the empirical formulas of the influence line of transverse load distribution.Finally,the reliability of the empirical formulas was validated by theoretical calculation.
