摘要：线路线形条件对高速铁路行车安全性及乘坐舒适性的影响显著增强。我国在制定高速铁路规范时,总结吸收国内外建设及运营管理经验,提出了较高的线形标准。采用动力仿真分析方法对高速铁路参数进行探讨,对高速铁路线路关键参数进行分析,提出线路平、纵断面关键参数合理取值。针对京沈高铁试验段开展更高速度综合实验,对线路线形方案开展动力学分析及评估。提出线路圆曲线、反向曲线夹直线最小长度、竖曲线最小半径关键参数合理取值,可有效减少工程建设投入;通过对京沈高铁试验段开展更高速度综合实验,对线路线形方案开展动力学分析及评估,提出通过增加8 000 m曲线半径超高的方法,提高速度400 km/h列车舒适度。
Abstract: The impact of the track linear condition on the safety and ride comfort of high-speed railway has been significantly enhanced. In formulating high-speed railway regulations, China has drawn upon domestic and international construction and operational management experience to establish higher linear standards. Adopting the method of dynamic simulation analysis, the parameters of high-speed railways are explored, and the key parameters of the railway alignment are analyzed, with the proposal of reasonable values of parameters of line horizontal and longitudinal section. A comprehensive experiment with higher speed is conducted on the test section of the Beijing-Shenyang high-speed railway, followed by a dynamic analysis and evaluation of the railway alignment scheme. The reasonable values for the key parameters of the railway alignment, including the circular curve, the minimum length of the straight line clamped with reverse curve and the minimum radius of vertical curves are proposed in this study, which can effectively reduce construction costs. By conducting comprehensive experiments at higher speed on the test section of the Beijing-Shenyang high-speed railway, a dynamic analysis and evaluation of the railway alignment proposal are carried out. It is suggested to improve the comfort of trains traveling at 400 km/h by increasing the curve radius by an additional 8,000 m.
