摘　　要：用刚性横梁法计算非径向支承弯梁桥的荷载横向分布 ,在计算单梁挠度时考虑了主梁梁端非径向支承的影响 ,得到了更为精确的结果 ,根据影响参数 ,编制了相应的表格 ,方便工程设计人员查用 .同时 ,还得到了此类桥梁的一个重要性质———转动中心的轨迹 .Taking the effect of non-radial bearings in the beam-ends into consideration, the rigid-crossbeam method was used to calculate the load lateral distribution of curved beam bridge with non-radial bearings as to get more accurate results. Then according to some related parameters, the corresponding form was made to suit the engineering designer's convenience. And also the trail of rotating center was abtained, which is one of the important characters of multi-beam bridge.
