摘　　要：提出了单钢板混凝土组合板桥的新桥型。以某简支板桥为背景,用刚接板法计算了该桥型的横向荷载分项系数,同时用ANSYS软件建立了桥梁的上部模型,计算结果表明:刚接板法和有限元法求得影响线竖向坐标值平均相对误差的绝对值约为9%,用刚接板法求解单钢板混凝土横向荷载分布系数合理、可行。As a new type of bridge,the half steel plate reinforced concrete slab bridge was proposed.A simply-supported slab bridge was taken as an example to calculate lateral load distribution coefficient of this type of bridge by the rigid joint method.Meanwhile,the upper model of the bridge is established by ANSYS software.Results show that the average mean error is about 9%.Thus,using the rigid joint method to calculate lateral load distribution coefficient is reasonable and feasible.
