连续曲线箱梁桥结构的桥梁自引入我国后,推动了我国桥梁建设的发展,为桥梁建设事业做出重要的贡献,促进了我国经济的发展。曲线箱梁桥具有弯扭耦合的力学特显,并对决定了桥梁的变形以及支反力、梁体受力、墩台受力三个力量的变化特点。文章最后简单叙述了连续曲线箱梁桥设计和计算时要注意剪力滞效应、支座脱空、径向力效应三个问题。
Since the introduction of the bridge with continuous curved box girder bridge structure in our country, it has promoted the development of bridge construction in our country, made important contribution to the bridge construction and promoted the economic development of our country. The curved box girder bridge has the mechanical characteristics of bending and torsion coupling, and determines the characteristics of the deformation of the bridge and the three forces of the supporting force, the beam body and the abutment. At the end of the article, three problems of shear lag effect, bearing vacancy and radial force effect are noticed in the design and calculation of continuous curved box girder bridge.
