摘　　要：以三跨简支转连续预应力混凝土T型简支梁桥为例,采用比拟正交异性板法计算桥梁横向分布系数,分析桥梁翼缘板宽度对横向分布系数的影响,得出主梁宽度与横向分布系数的关系,同时基于公路上普遍运行的3种重载汽车轮距布置最不利荷载,分析汽车轮距对横向分布系数的影响,得出汽车轮距与横向分布系数的关系。Taking a simply supported continuous T-beam bridge for example, use orthotropic plate simulation method to calculate the transverse distribution coefficient. Analyze the affect of flange plate width on transverse distribution coefficient, draw the connection of main beam width and transverse distribution coefficient. Simultaneously, in view of the three kinds of tire distance of the overloaded car generally run on the road, analyze the affect of tire distance on transverse distribution coefficient, draw the connection of tire distance and transverse distribution coefficient.
