摘　　要：针对跨座式单轨交通应急轨道梁走行面的超高调整方式进行研究.在确定应急轨道梁超高调整方式之前,首先对跨座式单轨交通原PC轨道梁走行面超高的设置规律进行分析和总结,然后根据原PC轨道梁走行面超高的设置规律确定应急轨道梁超高的调整范围和设置方式.最后从超高时变率对行车舒适性的影响出发,探讨了应急轨道梁走行面超高调整方式对行车舒适性的影响,并对应急轨道梁的行车控制速度做出了推荐.This study focuses on the superelevation adjustment of monorail transit emergency track beam. Before determining the mode of the superelevation adjustment, first of all, the straddle monorail transit original PC track beam superelevation setting rules were analyzed and summarized. Then according to the original PC track beam superelevation setting rules, emergency track beam superelevation adjusting range and setting mode were identified. Finally, from the influence of departure superel- evation changing rate on the driving comfort, the mode of superelevation adjusting rationality was investigated, and driving control speed of emergency track beam was recommended.
