摘　　要：道岔是高速铁路关键基础设施之一,我国铺设了CN(德国)、CZ(法国)和客专线(中国)3种技术系列的高速铁路道岔。截至目前,3种技术系列的道岔均经历了8年以上的运营实践,总体状态良好,满足高速行车需求。但运营中也暴露出道岔区车体异常晃动、轨道部件伤损频繁、钢轨快速磨耗等问题,影响道岔区动力学性能。对道岔区存在的问题进行总结分类,并阐述形成机理及应对措施,为相关研究提供借鉴。Turnout is a critical component of high speed railway. Currently there are three series of highspeed turnout applied in China, namely CN （Germany）, CA （France） and PDL （China） series. So far, all these three series of turnouts have been in service for more than 8 years, having shown good perlbrmance to meet the requirement of high-speed operation. However, some issues also exist, such as abnormal vibration of carbody in the turnout section, more damages of track components, early wear of rail, etc, which might impact the dynamic performance of high-speed train in the turnout section. The issues existing currently in the turnout section are classified and corresponding countermeasures proposed for reference of relevant research.
