| 自波纹钢腹板箱梁桥出现以后，由于其独有的轻质高强的优点已被广泛运用到工程实践中，然而对该单箱多室宽桥面桥的荷载横向分布系数计算并没有一个明确的概念公式。在对传统刚接梁法的研究修正基 础上，推导给出了实用于单箱三室的波纹钢腹板箱梁桥的横向分布系数算法，并通过建立 ansys 有限元模型进行分析和数值计算得到了验证，同时考虑了横隔梁设置对此类桥型的横向分布系数的影响，并分析得出了沿桥跨方向横向分布系数的变化规律。从而给出了具体的算法，支座处采用杠杆原理法计算结果，L/32 到 31L/32 采用修正的刚接梁法计算结果，支座到到 L/32 跨则采用线性过渡，为近似工程设计提供了理论依据。 |

| Since the arrival of corrugated steel webs girder bridge，due to its unique advantages of light weight，high strength has been widely used in engineering practice.But the calculation formula for load transverse distribution factors of a single box multi-cell bridge with wide bridge has not had a clear concept. Based on the research and correction of the traditional rigid connected beam method，the calculation formula for load transverse distribution factors has been deduced to apply for the 3 single box three-cells girder bridge with corrugated steel webs，and has been verified through the establishment of the ansys finite element model analysis and numerical calculation. At the same time considers the transverse beam insulation set its influence on the transverse distribution factors of this kind of bridge，and analyzes the changes of the transverse distribution factors along the bridge span.So the particular algorithm is given，the results of lever principle are applied to the bearing，the results from L/32 to 31L/32 are calculated by modified rigid beam method， the support to L/32 span adopts linear transition，so provides a theoretical basis for the similar engineering practice. |
