基于重交通条件下曲线桥梁施工关键技术

Key Technologies for Curved Bridge Construction under Heavy Traffic Conditions

重交通条件下,曲线桥梁施工难度进一步增加。为了给重交通条件下的曲线桥梁施工提供一些参考,利用案例分析法,以一个曲线桥梁施工工程为例,分析了重交通条件下的曲线桥梁施工问题,并提出了几条针对性解决技术。得出:重交通条件下,曲线桥梁偏心风险较大,可以利用下行线移动模架外侧加固+上行线顶推复位技术进行调整,有效解决桥梁偏心问题。

Under heavy traffic conditions,the construction difficulty of curved bridges further increases.In order to provide some reference for the construction of curved bridges under heavy traffic conditions,a case study method was used to analyze the construction problems of curved bridges under heavy traffic conditions,taking a curved bridge construction project as an example,and several targeted solutions were proposed.It is concluded that under heavy traffic conditions,the risk of eccentricity of curved bridges is relatively high.The adjustment can be made by using the technology of reinforcing the outer side of the moving formwork on the down line and pushing and resetting the up line,effectively solving the problem of bridge eccentricity.
