既有铁路线上跨连续梁调坡顶升关键技术研究

Key Technology Research on Highway Continuous Beam Bridge Crossing over Existing Railway

桥梁同步顶升技术在旧桥改造中近些年有广泛的应用,本文针对跨越既有铁路线的公路连续梁桥为对象,从顶升的几个技术参数方面进行计算分析,并进行了详细设计。所得成果在同类桥梁改造中有一定的参考价值。

The bridge synchronous lift technology has been widely used in reconstruction of old bridge recent years.Existing railway line crossing over the highway continuous beam bridge is regarded as the object,several technical parameters of jacking are also calculated and analyzed and detailed design is done.The results have certain reference value in similar bridge reconstruction project.
