摘　　要：对某地铁用60 kg/m钢轨9号单开道岔,分别计算限位器间隙为7 mm和10 mm时,轨下基础为碎石和整体道床的情况下,基本轨内最大温度力、尖轨尖端位移、限位间隙及温度力随轨温的变化情况。为地铁用60 kg/m钢轨9号无缝道岔的转辙器部分受力分析及限位器间隙的设计提供参考。For a 60 kg/m rails No.9 simple turnout used in subway,in the case of ballast and ballastless rail foundation with 7 mm and 10 mm anti-creep device gap,calculate the largest temperature force in stock rail,the displacement at switch rail tip and the gap of anti-creep device,which changed with the variation of rail temperature.Supply reference for the analysis of switch force and the design of anti-creep device gap in the 60 kg/m rails No.9 seamless turnout used in subway.
