结合具体工程实例,对曲线连续刚构桥进行结构分析。结果表明:“弯-扭”耦合现象使得曲线连续刚构桥的受力性能与直线桥有明显差异。对小半径、大跨径的曲线刚构桥,有必要对其进行空间结构分析,以更好了解结构的实际受力性能;对半径和跨径比本桥更接近于直线的桥梁,将其简化成直线桥设计,仍然具有很强的理论基础。
With concrete engineering examples, the structural analysis of continuous rigid frame bridge is carried out. The results show that the coupling behavior of “bend-torsion” makes the stress behavior of continuous rigid frame bridge significantly different from that of straight-line bridge. It is necessary to analyze the spatial structure of curved rigid frame bridge with small radius and large span to understand the actual mechanical performance of the structure better. For a bridge with a radius and span that is closer to a straight line than the present bridge, Simplify into a straight-line bridge design, still has a strong theoretical basis.
