| 摘 要： | 为了进一步深入研究拱梁组合式连续梁桥的横向分布特性，以龙溪大桥为背景，采用空间有限元的分析方法，对拱梁组合式连续渠桥的横向分布特性及沿纵向的变化规律进行了研究，并与传统计算刚架拱桥的简化弹性支撑连续梁法进行对比。对比分析后认为，两种方法结果吻合很好，在实际设计拱梁组合式连续梁桥时，横向分布系数计算可以采用弹性支承连续梁简化方法。

| Abstract: | To further study lateral distributional characteristics of a prestressed concrete continuous girder and arch combination bridge. Longxi bridge is taken as the case, study, the lateral distributional characteristic of a prestressed concrete continuous girder and arch combination bridge and variation along longitudinal direction are analyzed by using spatial finite element method, and the analysis results are compared with those of traditional calculation method for simplified elastically supported continuous girder. The results from the two methods are consistent, so that the simplified elastically supported continuous girder method can be used for the calculation of the lateral load distribution, in the design of continuous girder and arch combination bridge. |
