摘　　要：道岔是铁路轨道的重要组成部分,它的作用是引导机车车辆由一条线路转向或跨越过另一条线路,道岔构造复杂,是线路的薄弱环节之一,尤其是9号复式交分道岔,2019年以来,全路接连发生4起9号复式交分道岔护轨部分脱线事故,为更好的吸取教训,防止类似事故发生,结合现场调查对可能造成脱线的原因进行了认真分析,研究具有针对性的检查整修措施。Turnouts are an important component of railway tracks,and their function is to guide locomotives and vehicles to turn or cross another line.Turnouts have complex structures and are one of the weak links in the line,especially the No.9 double turnout.Since 2019,there have been four incidents of derailment of the No.9 double turnout guard rail on the entire line.In order to better learn from lessons and prevent similar accidents from happening,combined with on-site investigations,a careful analysis of the possible causes of derailment has been conducted,and targeted inspection and repair measures have been studied.
