摘要:
为解决高速铁路连续刚构拱桥施工误差导致桥面轨道静态长波不平顺性不满足规范要求的问题,拟定了调整轨道扣件厚度、轨道不平顺适应性基准设计温度、线路设计线形、吊杆力4种施工误差调整方案,对调整前后的桥面轨道静态长波不平顺性状态进行研究。研究结果表明:通过调整轨道不平顺适应性基准设计温度、线路设计线形及吊杆力,均可有效减小施工误差值。虽施工误差仍呈锯齿状、无规律分布,但均可满足规范轨道静态长波不平顺要求。其中,调整吊杆力方案可灵活选择吊杆力,理论状态误差调整效果最为明显,但现场施工工序繁琐、控制难度大,一般不建议采用。
Abstract:
To solve the problem that the static long-wave irregularity of bridge deck tracks does not meet regulatory requirements due to construction errors in continuous rigid-frame arch bridges for high-speed railways, four adjustment schemes for construction errors were proposed: adjusting the thickness of track fasteners, the benchmark design temperature for track irregularity adaptability, the alignment design of the track, and the suspension rod forces. The static long-wave irregularity of the bridge deck track before and after adjustment was studied. The research results indicate that the construction error value can be effectively reduced by adjusting the benchmark design temperature for track irregularity adaptability, the alignment design of the track, and the suspension rod forces. Although the construction errors are still serrated and irregular, they can meet the regulatory requirements for static long-wave track irregularity. Among these schemes, adjusting the suspension rod force offers flexibility in selecting rod forces and demonstrates the most pronounced error adjustment effect in theory. However, due to the relatively complex on-site construction process and high control difficulty, it is generally not recommended.
