针对武汉至黄石城际铁路线路具体设计情况,分析了超高作用机理和计算方法,按照铁道部文件《关于新建客运专线铁路曲线超高设定的指导意见》(铁集成[2009]86号),确定了武汉至黄石城际铁路超高设计原则,按照正确的计算方法,采用均衡速度匹配超高的思路,对武黄城际铁路的曲线超高进行了计算设置。计算结果表明,曲线超高设置合理,过超高、欠超高、超高顺坡率和超高时变率等限制条件均满足要求,保证了内外两股钢轨受力均匀和钢轨磨耗均等,提高了线路铺设无砟轨道高平顺性和安全性,满足了旅客的舒适性。
According to the specific design of Wuhan-Huangshi inter-city railway line, the mechanism and calculation method of ultrahigh speed are analyzed. According to the Guiding Opinion of Ministry of Railways on setting ultra-high of railway curve of new passenger dedicated line (TieGongCheng [2009] No.86) The principle of ultrahigh design of Wuhan-Huangshi inter-city railway was determined. According to the correct calculation method, the curve of ultra-high in Wuhuang inter-city railway was calculated and set by using the idea of equilibrium speed matching is very high. The calculation results show that the reasonable setting of the ultra-high curve, the conditions of over-high, under-high, super-high slope and ultra-high time-varying rate and so on meet the requirements, which ensure that the internal and external two strands are evenly loaded and the rail wear is uniform, The laying of ballastless track high-ride track and safety, to meet the passenger comfort.
