武汉至黄石城际铁路超高设置研究

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。

Study on Cant Setting for Wuhan-Huangshi Intercity Railway

According to the specific design situations for Wuhan-Huangshi Intercity Railway Line, this paper analyses the cant function mechanism and calculation method. In light of the Document Directives on Curve Cant Setting of New Passenger Dedicated Railway Construction （ TJC No. 2009 ] 86） by the Ministry of Railways, it finalizes the cant design princi- ples for Wuhan-Huangshi Intercity Railway. With correct calculation method and the concept of balanced speed matching the cant, it carries out the calculation and setting for the curve cant of Wuhan-Huangshi Intercity Railway. The calculation result shows that the curve cant setting is rational, and furthermore, the restriction conditions such as cant excess, cant deficiency, cant runoff elevation rate and cant time change rate all reach the requirements, which guarantees the even loading of both the inner and the outer rails and the equal wearing of rails, thus improving the regularity and safety of the track and fulfilling the passenger comfort.
