摘要
为满足30 t轴重重载道岔设计需要,采用了预埋铁座扣件系统,分析结果表明:推荐方案在岔枕表面应力和最大拉应力方面都优于其他两个方案,在新建铁路应用,效果良好。
To meet the design demand of 30 t axle load turnout,the fastener system with embedded iron base is adopted. The analysis results show that the proposed scheme is superior to other schemes on surface stress and maximum tensile stress for turnout sleeper,and its application effect is good in newly built railway.
