针对汕头国际集装箱码头重型钢轨的焊接问题，对高碳高强合金钢中的重型钢轨用常规的手工电弧焊焊接工艺进行了研究。

According to heavy-duty rail welding of containers at the port of Shantou , this paper studied high-carbon high-strength alloy-rail welding by using regular manual electric arc welding technology .

为提高钢轨的耐磨性能和滚动接触疲劳寿命并保证列车在高速重载条件下的平稳运行，各国正在采用新一代高强度、高韧性、高精度、可焊接的超长重型钢轨。

To increase the wear resistance and rolling contact fatigue life and to ensure the train smooth-running under high speed and heavy haul condition , a new generation of ultra-long rail has been developed with its high strength , high toughness , high geometry accuracy and good weldability .

使用较重型的钢轨有利于减小钢轨和轨道板的动力响应；

With the increasing of rail type , the dynamic response of rail and slab decreases ;
