摘要
电气化铁路接触网支柱在大风作用下的稳定性直接影响接触网系统的安全性和可靠性。目前各规范计算接触网支柱风荷载的方法基本一致,但不同规范计算公式中给出的参数取值却有所区别,因此计算得到的风荷载也不相同,最终影响所设计接触网支柱的抗风性能。对各规范中接触网支柱风荷载计算方法及参数取值进行研究,给出其计算公式中各参数取值的建议,并对目前铁路采用的接触网支柱抗风性能进行分析研究,提出设计接触网支柱时应采取的加强措施。
The stability of OCS post of electrified railway during high wind will have direct influence on safety of the entire OCS system. Currently the methods proposed in different codes and specifications for calculating the wind load of OCS post are basically the same, while the parameters used in different formulas vary a lot, causing different results of the wind load and different performance of the OCS posts. The paper studies the calculation methods and parameters in different codes and gives suggestions on selection of the parameters. The wind-resistant performance of current OCS posts is also analyzed and corresponding reinforcement measures proposed.
