摘　　要：由于制作和安装精度影响,无砟道岔转辙器部位可能会出现轨距偏小的现象。对沪宁客运专线无砟道岔进行现场静态测试,测试结果表明:在道岔转辙器部位出现轨距偏小的现象。对轨距偏小进行定量分析以及制作和安装的累计公差进行详细分析,并且提出了相应的解决办法。Owing to the effect of the precision of fabrication and installation,in the switch of ballastless track turnout there may appear shortened gauges.Through the in-situ static test on the ballastless track turnout of Shanghai-Ningbo passenger dedicated line,results showed that in the switch of turnout there appeared shortened gauges.Through quantitative ananlysis on the shortened gauges and detailed analysis on the cumulative fabrication and installation tolerances,the corresponding solutions were put forward.
