摘　　要：针对冬季铁路隧道内存在的冰柱影响铁路接触网安全的问题,文中提出一种使用激光器照射、加热并融化冰柱根部使冰柱坠落的方法。相较于人工除冰或电加热设备防冰,该方法设备主体小、能耗低、安全性更高,且可针对特定位置作业;在有效提升除冰效率的同时,还能保证作业工人的人身安全。仿真计算结果和现场实验结果均表明该方法可行且有效。In allusion to the problem that icicles existing in railway tunnels in winter can affect the safety of railway catenary,a method of using laser to irradiate and heat the roots of icicles to make them fall is proposed.In comparison with manual de-icing or anti-icing of electric heating equipment,this method has a smaller equipment body,lower energy consumption and higher security,and can be applied to specific locations.This method can ensure the safety of workers,while effectively improving deicing efficiency.The simulation calculation results and field experimental results show that the method is feasible and effective.
