斜靠式钢箱拱桥稳定承载力及成桥试验

Stability Analysis and Finished Bridge Test of Leaning-type Steel-box Arch Bridge

摘要:

斜靠式拱箱桥为采用主拱、斜靠拱、横撑和系梁形成的空间受力体系。以主跨145 m斜靠式钢箱拱桥为工程背景，研究分析其稳定承载力。有限元分析和成桥静动载试验表明：斜靠式钢箱拱桥具备足够的稳定承载力,大桥受力性能良好。

Abstract:

The leaning-type arch box bridge is a spatial stress system composed of leaning arch, cross-brace and tie beam. Taking a leaning-type steel-box arch bridge with the main span of 145 m as the engineering background, its stability bearing capacity is studied and analyzed. The finite element analysis and the static and dynamic tests of the finished bridge show that this kind of bridge has the enough stability bearing capacity and good mechanical behavior.
