摘要
工程实际中混凝土连续弯梁桥得到广泛应用,主梁"横向爬移"是混凝土连续弯梁桥的典型病害。论文回顾了弯梁桥横向爬移的研究现状,总结了弯桥的结构特征。以郑州环城高速某匝道桥为例,建立有限元模型。对不同荷载作用下支座支反力进行分析,对比均匀温度与梯度温度单独作用下对横向爬移量的贡献。
In practical, engineering concrete continuous curved girder bridge girder is widely used, 'Horizontal Creeping' is a typical disease of concrete continuous curved girder bridge. This paper reviews the research status of the horizontal creeping of curved bridge, summarizes the structure characteristics of curved bridge. Taking a ramp bridge of circular expressway in Zhengzhou, paper establishes the finite element model,analyzes the bearing force under different load, compares the effects on horizontal creeping of uniform temperature and gradient temperature.
