摘要
针对桥梁工程施工中跨越现有陆地交通道路与既有线路的相互干扰问题,提出了把连续梁转体施工方法应用到跨陆地交通道路和既有线路的桥梁施工技术中,保证了将桥梁结构置于障碍物外或靠近地面的障碍物上,从而降低了施工安全性风险和桥梁施工难度,节省了施工成本。文章结合具体工程实例,分析了桥梁转动体系施工技术,总结与探讨大跨度连续梁桥转体施工原理和施工方法,提出了大跨度曲线连续梁桥转体施工与称重的关键技术问题,为以后类似桥梁工程施工提供技术参考。
In order to solve the problem of interaction between the existing road and the existing line in the bridge construction,this paper puts forward a bridge construction technology based on the continuous beam rotating construction method.The method is applied to the bridge construction of the existing road and the existing line,guaranteeing that the bridge structure is placed on the barrier outside or near the ground,thus reducing the construction safety risk and the bridge construction difficulty,and saving the construction cost.Based on an example of concrete project,the construction technology of the bridge rotation system is analyzed,and the construction principle and method of the rotation construction of the long-span continuous beam bridge are summarized and discussed.The key technology of rotation construction and weighing of long-span curved continuous beam bridge is proposed,providing technical reference for similar bridge construction in the future.
