单跨斜箱梁桥设计计算研究

随着国家路网的不断发展,出现了各式各样的斜交桥梁。对于单跨密肋密支座整体斜箱梁桥,斜交角度大于20°时斜桥效应将非常明显,因此按照正交桥设计会留下很大的安全隐患。该文通过大量计算分析对比,提出计算斜桥的有效方法(梁格法)的同时,总结出一些能够缓解斜桥效应的有效途径,并对可能出现的斜桥病害提出可行有效的预防方法。

Study on Design and Calculation of Single-span Skewed Box Girder Bridge

With the continuous development of the national road network,there will be various skew bridges.The effect of skew bridge when the skew angle is larger than 200C is very obvious for the single-span dense rib dense support integrated skewed box girder bridge.Therefore,there will be the great safety hidden danger according to the design of right bridge.Through a great deal of calculation,analysis and comparison,the article puts forward the efficient calculation method(grillage analytical method) of skew bridg...
